It isn't possible to ban encryption, so the governments have to chip away at security and privacy using these techniques.

"You may also need to upload official government ID."
This won't end well for Google or the governments involved when the people get so angry that they are forced to roll this back. Switch to an alternative phone OS.
I don't think that's it. The desktop OS situation has historically be similar with 2 major large players and a bunch of insignificant ones.
This comes down to user expectation.
There are two OS platforms for desktop/laptop usage: MacOS Windows
These both contain ways to run arbitrary compiled code from an arbitrary source -- like a computer should. Losing this feature of our smartphones should have everyone concerned.
And they're both working towards taking that away.
For now we have Linux as a 3rd option, but that only exists so long as there's hardware available that'll let you run it. Can easily imagine a near-future where you can only get 'Windows hardware' or 'Apple hardware' and nothing modern that'll boot a 3rd-party OS.
For precedent, Microsoft locked down their own ARM hardware to Windows.
