And then they could offer apps, which (again I don't want this, just asking), could also be distributed if verified. F-Droid would have to be verified and would only be able to distribute apps from developers that are also verified.
And so conceivably you could still install apps from outside the Play store if they're verified. Unless the Play store is administering verification.
I'm not saying that would work, in fact, I think in practice it wouldn't. I'm just trying to play out what that would look like to understand the specifics of how F-Droid is being effectively dismantled. But I'm all ears if someone has a different interpretation about how F-Droid lives through this. It would seem that it would only survive on degoogled phones.
