If you've accidentally become a persona non grata, then obviously because you've not exercised sufficient self-censorship.

This is real already. Recently saw a petition for EU to rein in big tech (there are several initiatives advocating this). Had this nagging voice at the back of my head ... what if signing that gets your Google Account terminated.

I'll leave it open to you whether I signed it.

For developers relying on any type of Google services, you'd be in for lots of pain.

It doesn't even have to be censorship of speech.

If you are wrongly charged a significant amount by either Google or Apple and their service is of no help, what would you do?

Most people would weigh the options, then just eat the cost than anger them with a chargeback and lose their email/phone access. That's self-censorship financially too.

What if Google reinstates their old G+ and YouTube real name policy for its accounts. We would protest but give them the proof grudgingly and it can position itself as one of the core part of online ID verification push currently going on.

Google had Don’t be evil motto just between 2000 and 2018. Other companies don’t even try to pretend it. You are owned by them.
