"Google shouldn't have restricted Android, that's their (anti-user) choice, isn't it????"
The other party shouldn't be able to unilaterally chance the terms. It is my phone, after all, and I strongly believe I should be able to do whatever I can with the devices I own.
Even then, what other choice for an usable but actually of property of the user phone do you suggest? iPhone?
It's also extremely convenient for Google, a company lobbying ID laws, to add ID harvesting; or for Google, a company pushing for anti-user behaviour to add anti-user behaviour. If this was about security, they would stop shipping spyware, and take security seriously, something they do not.
