What US company doesn't cooperate with the NSA? Google responds to lawful requests by the US government as appropriate. It's up to US citizens to change the law if they don't like it.
Google does not sell data to anybody. They sell advertising slots.

yeah, the are clever when is about getting your info.
Programmatic algorithms on some Google properties are processing your data to show you the most relevant content (search, G+ posts, mail, news etc) and advertisements. There is a big difference between this "tracking" and the kind of snooping that spy organizations do.
By the way I'll be surprised if all spy organizations and not just NSA aren't trying their best to get more information on certain people from wherever they can.
