What the tech giants want is OS level attestation. They want to control what you can install on your device, to me the thing to avoid at all costs. This is not it, this is an open source app that you can run anywhere.
The proposed solution is the closest you can get to one that is designed to protect kids more than to control online activities. The weakness of the system, where a determined kid can get through is a feature, not a bug! More than that and it becomes more about control and less about kids (who will get through no matter what).
I am not commenting on how necessary age verification is. Personally, I am all for a wide open internet but many people actually want to "protect the children". The argument wouldn't be used as a justification for surveillance laws if they didn't.

And here's from the larger organisation, from another angle: https://techoversight.org/2025/07/29/bloomberg-meta-google-l...
The service for EU age verification app requires Google Play Integrity API check. So as much as you "can" run the app itself anywhere, you are forced to do it on whitelisted build of an OS on a whitelisted device.
