...and yet because there's only Apple and Google providing hardware that's used by the masses, exactly how is this going to work? If the environment we're using is completely contained (pwned) then how will this not be a draconian system of control?

What happens when I buy debian mobile? I presume it will not be accepted because there will be no safe app. No app, no identity? No identity means you're suddenly locked out of society.

What phone theft? Most people's phone security is almost non existent.

What about luddites who have no mobile at all?

It seems like it's 100% about control of people. And that's a privacy matter. My body, my life, my choice.
