Ex-Facebook insider says covert data harvesting was routine
Do we actually know what data has been leaked/illegitimately retained/whatever you call it?A lot of the discussion revolves around friends data -- was all friends data accessible regardless of the friends' own privacy setting (this would be deeply troubling), or was it the data that friends shared with the app users (a bit less troubling, but still very questionable), or was it friends' data that was openly available on their public profiles open to any internet user?
