> What I think is wrong, is then for facebook (or other apps) to sell, or leak that data in enough detail to match to our identity where it can be used for other purposes. That's what everyone thinks is wrong. FB (and Google, and LI, etc) already tell you they won't use your data for other than ad purposes and that they won't resell your data as PII. The problem is a) policing it b) in case of inadvertent disclosure, there's no remedy. privacy compromises are permanent. To date, it's a tradeoff we (society) have been willing to take.
