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.
