I don't understand how this is legal in the EU under the DMA, does anyone know?

I already contacted the DMA authorities and complained how this has an effect on German diabetes communities and they replied that I am not the first one who approaches them on this and they are already investigating it.

Google is just trying how far they can push this.

Do you have any pointers on how to find the correct authority and reach out? I'd like to inform my EU audience.

Excellent, I emailed them too but no reply yet. Yeah, given that we should be able to choose what app store to install, this seems wildly illegal.

https://www.eu-digital-markets-act.com/Digital_Markets_Act_A... Art 6 (4). Read it to the end. That's how.

I don't get what part of that your think enables them to deny access to third parties distributing their apps on alternate stores. If you're referring to the last paragraph, that very explicitly says that any such security must be an optional setting that is not default. So unless users opt into verified only apps, Google can't force that, according to the DMA.

Maybe not, but reading their blog posts about ADV next to the DMA text, that's certainly the angle they are trying. And it will be years if it ever comes to a court hearing.

And the setting is "optional", just do the 24h-waiting song and dance to change it, or use ADB. /s

The same way Apple is allowed to do it presumably.

It's not.

This is arguably required by Article 30 of the EU Digital Services Act.
