So the user can't install what they want. They can only install stuff signed by developers Google has "approved".
Yes, in the happy situation this is everything except for developers that Google has revoked. But technically it is only approved developers.
> That users won't be able to install what they want and that they would need a google account to install apps
It was split up because "need a Google account to install apps" is strictly untrue, but "won't be able to install what they want" is more nuanced.
I did clearly say, "it won't work if the APK isn't signed by someone in the Google developer registry".
So, it depends on what the user wants.
If they're running certified Android; otherwise it doesn't matter.
It is only for registered developers, so of course that very much depends on the registration system.
