They won’t affect Android builds that aren’t Google-certified directly.

They’ll affect F-Droid in that most people won’t be able to install most apps from F-Droid without an obnoxious process and a waiting period. That will affect what people spend their time building and will likely result in fewer open source apps being created and maintained.

GrapheneOS and LineageOS don’t ship with any Google services at all, so Google’s policies shouldn’t affect them.

Don’t Panic ,just wait en see.

The OSs aren’t forks as far as in aware. So this turd in the water will flow downstream and then it depends. Can they excise this dev database checkup? Or will they fork (or at least try)? I think we have to wait and see.

The availability of apps will probably decrease. Although with the latest advanced flow of the turd that will allow installation after a 24h cooling off period, a restart, a piece of your soul, and your firstborn it will probably not be a bad as we had initially thought. Still shit though.

There is no way in hell that this checkup Google will conduct will be looked at by actual people. This will be automated. I predict this will be a cat and mouse game where hackers will find a way to bypass this, Google will find out and fix it, whereupon hackers will find a way to bypass that, and so forth. As Google will be the mouse in that game, they might tire of it.
