The richest technology company in the world cannot ship its flagship AI assistant to the iPhone in its second-largest market, but it can ship it to a headset almost nobody owns. That is not a mistake or a negotiating tactic. It is the DMA working exactly as designed, and the consequences extend far beyond which devices light up with AI. This is one dimension of the wider Siri AI and DMA story.
The platform split exposes a regulatory framework that demands platform-level interoperability from an architecture built on the opposite premise: that the operating system owner controls the execution environment to guarantee privacy. Neither side designed for the other, and neither appears willing to redesign. What follows is a walk through the dispute, from the surface anomaly to the regulatory engine, the failed negotiation, the financial exposure, the historical pattern, the competitive landscape, the legal endpoint, and the geopolitical dimension that turns a product fight into a template for global AI regulation.
Why can Vision Pro and Mac users in Europe access Siri AI while iPhone owners cannot?
Siri AI is blocked on iOS 27 and iPadOS 27 in the EU because these platforms are designated DMA gatekeeper core platform services. That designation triggers Article 6(7) interoperability obligations, Apple announced in June 2026, requiring the company to give third-party virtual assistants the same system-level access Siri AI enjoys. macOS 27 and visionOS 27 are not designated gatekeeper platforms. Vision Pro’s EU install base, estimated at 15,000 to 25,000 units, falls well below the DMA’s quantitative thresholds of 45 million monthly active EU users and €7.5 billion in EU turnover.
The contrast between roughly 0.006% of EU Apple users getting access and the 450 million who do not makes the split concrete. watchOS 27 loses Siri AI as collateral: the Apple Watch requires a paired iPhone with Siri AI, so the iOS block cascades to the wearable even though watchOS itself is not designated. This is not a loophole Apple exploited, as industry analysts noted. The DMA’s designation process assesses each core platform service independently using those quantitative thresholds, and it produces an outcome where the platform benefiting from the regulatory gap is the one almost nobody owns.
What exactly does the DMA’s interoperability obligation require?
That structural feature is Article 6(7), and understanding what it actually requires is the key to the dispute.
Article 6(7) requires designated gatekeeper operating systems to allow third-party virtual assistants to interoperate on equal footing with the gatekeeper’s own assistant. The gap between how each side describes the same requirement is revealing. Apple describes the Commission’s interpretation as requiring “nearly unlimited access” to user devices, including the ability to read messages and execute actions across any app, without the protections Private Cloud Compute was designed to enforce. The European Commission describes the same requirement as allowing users to choose which AI tools they use.
The practical problem is that neither side has defined what compliance looks like in technical terms. The Commission’s enforcement model is ex-post: it assesses implementations, not specifications. Apple’s position is that it cannot build to an unclear specification when the outcome affects tens of millions of users’ personal data. Beneath that semantic gap is a collision between two architectures: Private Cloud Compute guarantees no one other than the user accesses processed data, and DMA interoperability would introduce third-party AI models into that environment.
What is Apple’s Trusted System Agent and why was it rejected?
The Trusted System Agent was Apple’s proposed intermediary software layer that would let third-party virtual assistants access the same platform capabilities as Siri AI without direct, unfiltered access to user data. Apple proposed launching Siri AI in the EU immediately while rolling out the TSA over 18 months. The Commission rejected both the concept and the phased timeline, framing it as a request for an 18-month exemption from DMA obligations rather than a compliance solution.
The BrowserEngineKit precedent did not help Apple’s case. That earlier intermediary layer for third-party browser engines on iOS was criticised as performing poorly and locking in Apple’s gatekeeper role, so when Apple proposed another intermediary layer, this time for AI access, the Commission had reason to be sceptical. A Commission official later told the Financial Times that contact with Apple on the TSA was limited and lacked detail beyond the general concept. Apple SVP Greg Joswiak confirmed to Numerama that no engineers are currently working on the TSA. The only proposed bridge between the two positions has been abandoned.
What does a permanent Siri AI lockout actually cost Apple?
With the TSA abandoned and no compliance architecture in sight, the financial exposure becomes the next logical question.
DMA non-compliance penalties reach 10% of global annual turnover per infringement, rising to 20% for repeat offences. Against Apple’s FY2025 revenue of approximately $383 billion, the theoretical maximum fine approaches €35 to 38 billion per infringement. In practice, the Commission has not approached the statutory ceiling. The €500 million App Store anti-steering fine in April 2025 represented roughly 0.13% of Apple’s annual turnover, and Meta’s €200 million “consent or pay” fine fell in a similar range. The earlier €1.84 billion music streaming fine was under traditional antitrust, not the DMA.
A realistic estimate for Siri AI non-compliance sits between €1 billion and €5 billion, potentially escalating if the Commission treats it as ongoing non-compliance with periodic penalties. AI is a strategic priority for both Apple and the EU, making a more aggressive enforcement posture likely. The DMA’s Three-Year Review acknowledged that some impacts “remain not fully observable,” signalling the Commission intends to demonstrate the regulation’s effectiveness through enforcement. Beyond fines, Apple risks strategic erosion in a market representing roughly 27% of total sales. EU developers cannot build or test Siri AI integrations, and the competitive opening for Android AI rivals compounds with every quarter the lockout continues.
How does this compare to the 2024 Apple Intelligence delay?
Apple Intelligence was withheld from EU iPhones when it launched in the US in October 2024, citing DMA regulatory uncertainty. Those features, writing tools, image generation, notification summarisation, arrived with iOS 18.4 in April 2025 after months of compliance negotiation. The pattern, delay, negotiate, launch late, gave observers a template that suggested Siri AI would follow the same arc.
It has not, and the reason is structural. Apple Intelligence was a set of discrete features that could be negotiated individually. Siri AI is a monolithic system-level assistant whose cross-app awareness, personal context engine, and Private Cloud Compute integration make it architecturally indivisible. The Commission is demanding platform-level interoperability, not feature-level adjustments. The rhetorical escalation tells the same story: Apple’s 2024 statements were cautious, referencing “regulatory uncertainties.” In 2026, Apple SVP Greg Joswiak described the Commission’s position as “a very risky experiment on many, many, many tens of millions of users”. The 2024 resolution template does not apply.
How does Apple’s approach compare with Google’s on Android?
If this is a structural problem with the DMA rather than an Apple-specific dispute, what does Google’s experience on Android reveal?
Google’s Android is also a designated DMA gatekeeper core platform service subject to Article 6(7) obligations for Gemini. The regulatory symmetry is exact: both dominant mobile platform owners face the same requirement to open their AI assistants to third-party competition. But Google’s response has been different. The company assigned 3,000 people full-time for two years on DMA compliance for a single provision, signalling a strategy of building compliance incrementally rather than publicly confronting the Commission.
Neither company is shipping a DMA-compliant AI assistant in the EU. Samsung, Mistral AI, and other competitors have not produced an AI assistant that fills the void left by Siri AI and potentially Gemini. The asymmetry in public attention reflects different public relations strategies, not regulatory favouritism. The core observation applies equally to both: the DMA is imposing the same structural demand on both mobile platforms, and neither has found a way to satisfy it while shipping AI. This regulatory symmetry is a core thread in the broader Siri AI and DMA lockout picture.
What did the July 2026 court ruling actually decide?
On July 8, 2026, the EU General Court in Luxembourg rejected Apple’s challenge against its DMA gatekeeper designation for iOS and the App Store. The court ruled the Commission correctly applied the quantitative thresholds and that iOS constitutes an important gateway for business users to reach end users. Apple’s separate challenge to iMessage’s designation was ruled inadmissible.
The ruling eliminated Apple’s procedural path to escaping DMA obligations at the General Court level. Apple can appeal on matters of law to the Court of Justice of the European Union, but CJEU appeals typically take 18 to 24 months and Apple has not indicated whether it will pursue this. Appeals do not stay DMA obligations. Apple must comply or face fines while any appeal proceeds. The judicial escape hatch is closed.
Is this a one-off or the latest chapter in a longer conflict?
The Siri AI lockout is the third major DMA-driven feature restriction in roughly two years, following iPhone Mirroring and AirPods Live Translation blocks for EU users. But the escalation pattern is larger than individual blocked features. You can trace a clear arc: the 2024 Apple Intelligence delay (resolved through negotiation, modest stakes), the April 2025 €500 million App Store anti-steering fine (punishment, not negotiation), the July 2026 General Court ruling (legal route closed), and now the Siri AI lockout (neither side has a viable path forward). Each chapter removes an option, each resolution takes longer, and the stakes rise with each new Apple product generation.
The Free Software Foundation Europe documented that, by its count, of 56 formal DMA interoperability requests submitted to Apple, none resulted in a new solution being developed. Of 16 publicly disclosed closures, 10 were denied on technical grounds, two were dismissed as already solved, and three were rejected as out of scope. You do not need to agree with the FSFE’s characterisation to recognise the pattern: Apple’s posture toward DMA compliance has been consistent across features and across years.
The geopolitical dimension is escalating in parallel. The US Trade Representative is investigating whether the DMA discriminates against American technology companies under Section 301 of the Trade Act. The Information Technology and Innovation Foundation has published a detailed case for trade retaliation, proposing tariffs on EU goods. EU Competition Chief Teresa Ribera has described US pressure as “blackmail”. Meanwhile, DMA-modelled laws are proliferating: the UK’s DMCCA, Japan’s MSCA, Brazil’s Bill 4675/2025, and proposals in South Korea and Australia. The Siri AI outcome in Europe is becoming a template for AI regulation globally. The escalating conflict, from product delays to trade retaliation threats, is mapped in the fuller Siri AI and DMA regulatory picture.
The Siri AI platform split has become a permanent structure. Every path to resolution, compliance negotiation through the TSA, judicial challenge through the General Court, has been tried and closed. What remains is a standoff where neither compliance nor non-compliance is acceptable to both sides. Apple cannot redesign Private Cloud Compute for multi-tenancy without surrendering its privacy guarantee. The Commission cannot accept Apple withholding features without surrendering its enforcement credibility.
The duopoly’s bet, that non-compliance is cheaper than compliance and no challenger will exploit the gap, is holding for now. But every previous assumption about this conflict has been invalidated: that negotiation would work, that the 2024 template would repeat, that the courts would provide escape. The Siri AI lockout reveals the shape of the standoff, and that shape is now being exported worldwide.
When you read the next headline about Apple and the EU, you will see it as the next chapter in a structural conflict whose resolution may be measured in decades, not quarters. The standoff between Apple and the Commission over Siri AI is the template for how AI regulation will unfold globally, and the only safe prediction is that the next chapter will be more consequential than the last. The strategic implications for engineering leaders are only beginning to be understood.
Frequently Asked Questions
Can EU iPhone users access Siri AI by changing their Apple ID region or using a VPN?
No. Siri AI availability is determined by the device’s hardware region identifier set at activation, not by the Apple ID region or VPN location. Apple uses a combination of the device’s activation region, billing address, and physical location to enforce the block. Changing your Apple ID to a US region will not enable Siri AI on an EU-purchased iPhone, and a VPN cannot mask the hardware-level activation identifier that flags the device as DMA-regulated.
Will Apple ever bring Siri AI to EU iPhones, and is there a timeline?
There is no timeline and no active engineering work toward one. Apple SVP Greg Joswiak confirmed no engineers are working on the Trusted System Agent, and the July 2026 General Court ruling closed Apple’s procedural path to escaping DMA obligations. Resolution requires one of three changes: the Commission accepting a compliance architecture Apple finds viable, Apple redesigning Private Cloud Compute for multi-tenancy, or the DMA itself being amended. None appears imminent.
Does the Siri AI lockout affect EU iPad users too?
Yes. iPadOS is a designated DMA gatekeeper core platform service alongside iOS, so the same Article 6(7) interoperability obligations apply. Any iPad purchased or activated in the EU will not receive Siri AI. The split is between platforms that are DMA-designated (iOS, iPadOS, watchOS by dependency) and those that are not (macOS, visionOS), not between device categories. EU iPad users face identical restrictions to EU iPhone users.
What happens if someone buys a US iPhone with Siri AI and brings it to an EU country?
Siri AI will continue to function on a US-purchased iPhone brought into the EU, because the device was activated outside the EU’s regulatory jurisdiction. This is a grey area with no long-term guarantee. Apple could theoretically disable Siri AI based on sustained physical location detection, though it has not done so to date. The practical answer is that US iPhones work in Europe with Siri AI intact for now, but this is an individual workaround, not a scalable solution.
Is there a way Apple could technically comply with the DMA without sacrificing user privacy?
This is the central question behind the impasse. The Commission’s position, “build it and we’ll assess it,” means Apple cannot pre-clear a compliance architecture. The Trusted System Agent was Apple’s best attempt: an intermediary layer that would give third-party assistants access without direct, unfiltered access to user data. Its rejection suggests the structural problem is genuine. Private Cloud Compute’s single-tenant privacy guarantee depends on exclusive platform control, and mandated third-party model access at the platform level contradicts that premise without a fundamental architectural redesign that has no demonstrated solution.
What AI assistant can EU iPhone users turn to instead of Siri AI?
EU iPhone users are not locked out of AI entirely. Third-party apps including ChatGPT, Google Gemini, and Mistral AI’s Le Chat remain available through the App Store as standalone applications. What EU users lose is system-level integration: Siri AI’s cross-app awareness, personal context engine, on-screen awareness, and deep iOS integration. Third-party apps can answer questions but cannot act across apps, read the screen, or access personal data the way Siri AI can on non-EU devices. The gap is integration depth, not basic AI access.
Is Google’s Gemini facing the same EU regulatory block as Apple’s Siri AI?
Not in the same visible way. Google has not publicly announced withholding Gemini from EU Android devices, but nor has it demonstrated DMA-compliant AI interoperability on Android. The Article 6(7) obligations apply symmetrically to Android as a designated gatekeeper platform. Google’s quieter approach may reflect a different strategy: building compliance incrementally rather than withholding features publicly and framing it as a regulatory dispute. The absence of visible conflict does not mean compliance has been achieved, only that Google and the Commission are managing the process differently from Apple.
Can Apple just absorb the DMA fines and permanently keep Siri AI out of Europe?
In theory, yes, though the calculation is not simple. The statutory fines reach approximately €35 to 38 billion per infringement, structured to be punitive, but Apple’s market capitalisation exceeds $4 trillion. The practical deterrent is not a single fine but the threat of escalating periodic penalties for ongoing non-compliance, plus the strategic cost of ceding AI ground in a market representing roughly 27 percent of Apple’s total revenue. Whether the financial cost of compliance exceeds the cost of perpetual non-compliance is the unresolved question at the heart of the standoff.
What does this standoff mean for Apple’s business in Europe?
Beyond direct fine exposure, Apple risks strategic erosion in its second-largest market. EU developers cannot build or test Siri AI integrations, creating a developer ecosystem gap that compounds over time. EU consumers are excluded from Apple’s flagship AI experience while Android competitors build AI capabilities unopposed. The longer the standoff persists, the greater the competitive damage. Apple’s roughly €100 billion in annual EU revenue is not at immediate risk, but its AI relevance in the European market erodes with every quarter the lockout continues.
Could the US government intervene to protect American technology companies from the DMA?
The US is already exploring intervention. The Section 301 trade investigation, led by the US Trade Representative, is examining whether the DMA discriminates against American technology companies. The Information Technology and Innovation Foundation has advocated for trade retaliation including tariffs on EU goods. EU Competition Chief Teresa Ribera has described US pressure as “blackmail.” The Siri AI dispute is unfolding against a backdrop of transatlantic trade tension that could escalate well beyond technology regulation, making it a test case for how far the US is willing to go to defend its tech industry.
