I am the sort of person you are talking about (distrusts FB) and I do what I can to make others realize how evil they are. Case in point, somehow many people either missed the whole Beacon debacle entirely or have put it out of their minds until reminded. I will never understand how anyone can give ANY personal data (who friends are and so forth) to a company who has proven so... ruthless in using that data for personal gain without consideration of their user base.
