1.) Free speech is a completely different topic. Snowden's quote on this page makes no sense to me no matter how often I re-read it. If free speech didn't exist I wouldn't be able to express my opinion about privacy :)
2.) Privacy means hiding the truth. Hiding what really happened. Hiding who you really are. I believe it is a flaw of the human personality that makes us want to hide information and eventually lie about it.
I don't care if Google or the government knows that I'm searching "[insert embarassing keywords for you here]" or if Facebook knows my location, or if Twitter knows what I like based on the people I follow.
Who is the government? It's people. People like you and me. If people decide to make assumptions based on data they collected and the assumptions aren't correct it's their own fault for assuming something in the first place (because...you know...it's an assumption...it can be wrong).
I am not aggressively opposing the concept of privacy. I respect other people's opinion.
