Android's sideloading limits are its most anti-consumer move

Installing any app I want outside the Play Store was the primary reason I decided to go with Android, despite most of the people I know using iPhones. If I can't do this anymore, I may as well switch and be able to use iMessage and FaceTime with them.

You can still install apps outside the play store, but the developer does need to verify their signing information. Effectively this means that any app you install must have a paper trail to the originating developer, even if its not on the app store. On one hand, I can see the need for this to track down virus creators, but on the other, it provides Google transparency and control over side loaded app. It IS a concerning move, but currently this is far from 'killing' non-appstore apps for most of the market.

Pretty sure virus creators could just pick a real ID leaked by the "adult only logins" shenanigans, whereas legit app developers probably wouldn't want to commit identity fraud.

If it gets that bad; Google can do what they already do with business listings - send a letter to the physical address matching the ID, containing a code, which then must be entered into the online portal.

Do that + identity check = bans for virus makers are not easily evaded, regardless of where they live.
