You could of course sue Google, but that's an extremely expensive and time-consuming option, rarely worth it for a mere consumer. Going to court certainly won't make your suspended account become unsuspended any quicker.
I get where you're going, but I think far more costly to them and advantageous for us is to simply show them that they are unnecessary.
If we can drop them so easily, they can't pull stuff like this anymore. It is possible to drop Google and Facebook.
They do this stuff because people _need_ them and they know that people won't just drop them en mass.
Sometimes, it is so abundantly clear to me that this site is full of former teenage libertarians who grew up and still haven't shed all of those ideals.
