Of course I can't prove that Google hasn't done anything wrong. I don't believe that. Google is criticized all the time for various things they did. Sometimes they change what they do in response to criticism.

They also have a lot of power that could be abused. I like to make a distinction between potential and actual harm, though. Almost everything you do in civilization involves trusting other people to do things for you. Including keeping secrets. Sometimes that trust is broken, but a trustless society isn't possible.
