You seem to think that Facebook is any different from Google (or Microsoft, despite their bullshit statements to the contrary) as far as mining data for advertisers and the NSA is concerned.
I think the main way Facebook and Google are different, is that Facebook probably has even more information on its "customers" than Google does. Google is a search company, Facebook is a walled garden. Google wants to "organise the world's data", Facebook wants to own it all. Those, I think, are your main differences.
