A big win for Android interoperability

  • Regulation
  • Mobile
  • AI
  • Payments
  • Privacy

The post points to an EU ruling under the Digital Markets Act that requires Google to expose parts of Android that have been effectively reserved for Google Assistant and Gemini. The practical scope is narrower than the headline suggests. It is mostly about assistant-style access: wake-word handling, structured actions across apps, screen automation, background execution, access to system resources like the NPU, and equal use of on-device models. People reading the decision text came away with a clear view that this is not a general opening of Android. It is a targeted order aimed at letting rival AI assistants work with the same OS-level privileges Google gives its own products.

If you build on Android, expect more system-level assistant and on-device AI capabilities to become available to third parties in the EU first. But if your business depends on mobile openness more broadly, keep watching payments and Play Integrity remote attestation, because those are still the chokepoints that determine who can actually compete.

Discussion mood

Positive about the EU forcing open privileged Android features, but tempered by annoyance that the ruling is narrow and leaves the more important lock-in points untouched, especially payments, Play Integrity remote attestation, and OEM control over bootloaders.

Key insights

  1. 01

    NFC payments were never the hard part

    Android has supported bank-run NFC card emulation for roughly a decade, and commenters pointed to past and present examples from Europe, Australia, and Russia. The blocker is not an OS capability gap. It is that banks abandoned their own wallets because supporting them cost more than routing everything through Google Wallet or Apple Pay, which means payment lock-in is mostly an ecosystem and incentives problem, not a missing Android API.

    Do not assume regulation of OS hooks will produce open payments by itself. If you want an alternative wallet, the real work is bank, network, and commercial integration, not just Android engineering.

    Attestation is still the real veto

    Opening assistant APIs does little for anyone trying to ship or use an alternative mobile OS because remote attestation still lets banks and other apps reject devices that are secure but not blessed by Google. Commenters pushed the point further than simple inconvenience. Attestation changes who gets to decide what software may run on your own hardware, and even a reproducible build like GrapheneOS does not escape that if vendors insist on an allowlist of approved signing keys.

    If your product must run on custom ROMs or non-mainstream devices, track Play Integrity and similar attestation checks as a first-order business risk. Assistant interoperability is helpful, but attestation still decides market access.

    This ruling is mostly about AI assistants

    People who read the EU materials closely noted that the celebrated list of eleven features collapses into a handful of assistant-enabling capabilities. The order is about hotword activation, background execution, screen control, app actions, and equal access to on-device models and hardware resources. That framing matters because it means this is not a broad mandate to expose every privileged Android interface, and it does not automatically reach adjacent complaints like call screening, payments, or messaging stacks.

    Read this as a precedent for assistant and agent interoperability, not a blanket opening of Android internals. Teams planning around it should scope opportunities to voice, automation, and on-device AI workflows.

    Google is not the main bootloader villain

    Several comments pushed back on the idea that Google is the company preventing custom Android distributions from existing. On current Android hardware, Pixel is one of the few lines that is both unlockable and relockable with user-controlled keys, while many other OEMs either lock bootloaders completely or make unlocking impractical. That flips the usual story. Google’s service-layer control is a problem, but the hardware market is often even more hostile to user-controlled firmware.

    If you care about alternate firmware, separate hardware freedom from Google service lock-in in your strategy. The DMA can pressure Google on APIs, but device choice and OEM policies remain a separate bottleneck.

    RCS complaints often mean Google Messages complaints

    A detailed reply argued that RCS itself is more open than many people assume, but implementing a full client is messy because registration and carrier authentication tie into IMS and privileged SIM-facing functionality. The practical demand is not just for an open protocol. It is for Google to expose a maintainable API or open more of the stack that Google Messages already handles. That is why RCS feels closed even when parts of the protocol are published.

    When evaluating supposedly open standards on mobile, inspect where the privileged glue lives. A public protocol does not create real interoperability if the operational pieces still depend on vendor-only system access.

Against the grain

  1. 01

    The ruling misses the business model problem

    One skeptical view was that opening selected Google-only features barely matters if small vendors still cannot legally and practically buy phones, install modified Android builds, and sell them at scale. From that perspective, API interoperability is a patch over the deeper issue that alternative Android distributions remain structurally hard to commercialize because of locked hardware and anti-circumvention rules.

    If you are looking for market structure change rather than feature access, do not overread this decision. Watch for reforms around device resale, bootloader policy, and anti-circumvention law instead.

    Cards, not Android, are the real bottleneck

    A contrary line of argument said the mobile wallet dead end has less to do with Google than with the Visa and Mastercard duopoly and the consumer protections tied to card networks. Even a technically open Android wallet still has to persuade banks, issuers, and merchants or avoid cards entirely with options like QR payments over SEPA Instant. That makes the fight much bigger than phone OS interoperability.

    If you want payment innovation in Europe, spend at least as much time on rails and fraud guarantees as on mobile APIs. A better Android interface will not overcome card-network economics by itself.
