Here’s the thing about the EU’s latest move against Google and Apple: it’s not really about AI assistants. It’s about who controls the entry point to your phone — and increasingly, to every digital service you use.
European regulators have issued formal demands under the Digital Markets Act requiring both companies to open their AI assistant integrations. The core argument: when Siri and Google Assistant are pre-installed, non-swappable defaults on billions of devices, they create a structural advantage that competitors cannot overcome regardless of quality.
What the EU is actually asking for
The demands are specific. Regulators want users to be able to designate any AI assistant as their default — not just the one that shipped with the device. They want interoperability between assistant platforms, so a third-party AI can access the same device sensors and APIs that the built-in ones can. And they want no commercial pressure on device manufacturers to keep Google or Apple assistants front and center.
This sounds technical. It has enormous commercial consequences. Google Assistant and Siri are not just features — they are distribution channels. A user who asks their phone assistant to find a restaurant, book a flight, or set a reminder is triggering a chain of data collection, ad targeting, and platform preference that generates billions in value. That chain starts at “Hey Siri” or “Hey Google.”
Why both companies are pushing back hard
Google’s legal response emphasizes that users already have choice — they can download and use any AI assistant they want. Apple’s argument leans on security and privacy: allowing third-party assistants deep system access creates vulnerabilities that Apple’s controlled ecosystem is specifically designed to prevent.
Neither argument is entirely wrong. Users do have nominal choice. System access does create security considerations. But neither argument addresses the structural reality: when one assistant is installed by default and requires explicit action to replace, the overwhelming majority of users never replace it. Default is destiny.
The broader pattern
The EU enforcement action follows a pattern that’s become familiar: American tech companies build products that users genuinely love, scale them globally, and in doing so create structural advantages that regulators in Brussels eventually decide require intervention.
What makes this case different is the timing. AI assistants are no longer a mature market being carved up — they’re in rapid evolution. The assistant you use today will likely be fundamentally different in two years. Forcing open this market now, before patterns solidify, gives Europe more leverage than intervening in a decade when switching costs will be even higher.
What this means beyond Europe
The EU has a track record of setting global precedents. GDPR reshaped how companies handle data worldwide, not just in Europe. USB-C standardization on iPhones happened because of EU rules, not Apple’s preference. If the AI assistant interoperability requirements stick, device manufacturers everywhere will face pressure to implement similar openness.
For Google and Apple, the question isn’t whether to comply — they will, eventually. It’s how to comply in ways that preserve the core strategic value of their assistant ecosystems while meeting the letter of the regulation. That gap between letter and spirit is where the real battle will be fought.
