I don't think they explicitly promised privacy, but they didn't have any kind of disclaimer or openly say "we can and probably will sell the information you give us to advertisers."
Or at least they didn't when I signed up for about five or six years ago.
I was referring more to the position they took a while back that even if you delete stuff off your profile, they still have it. They backed off and said they would only keep it for 2 weeks further, but why believe them? Who's checking up on what happens to the data after you deactivate your account?
Zuckerberg has voiced open disdain for privacy concerns, so why should I believe FB took the concerns seriously?
