I am convinced it won't go anywhere. It is not prohibiting app installs outside the Play Store: it's enforcing that apps installed on certified Android devices are signed by a valid Play developer account.

If I understand it correctly, it means that you could get a valid developer account and never put your app on the Play Store. Instead people could sideload it.

This sounds very similar to mac apps that should be signed by valid apple dev account.

It is prohibiting in a few ways: relying on a company in a foreign country, and no alternative if your account gets randomly banned. Also what would happen to developers in embargoed countries?

Those are unacceptable to developers outside of the USA.

Those are good point!
