My uncle has lost 4 Google accounts. Two to password loss, one to a fire, one to being banned for crimes against currency (having the audacity to live in several countries with different currencies)

The issue isn't the phone, it's that a __government__ is depending on an unregulated private enterprise.

Are you saying there's a threshold percentage somewhere below which you're happy to

A: exclude these people from society or force them to switch to big tech, and

B: accept the consequence where a single other country holds access to everyone's identity information for convenience reasons (because it works for the 99% that are too tech-illiterate to install software that they control instead of the other way around)

I think the point is rather what percentage of people will continue to need to have a phone that is Apple or Google, due to death by a million decisions like these.
