This isn't meant to call you out specifically but I've seen others echo similar sentiments of "I only put what I want on FB so it's no big deal privacy wise".

This isn't meant to call you out specifically but I've seen others echo similar sentiments of "I only put what I want on FB so it's no big deal privacy wise". What's troubling about FB is the _other_ implicit information they (and the other large social apps) passively collect about you. Unless you're using a particularly effective ad/privacy blocker you're also sharing all the data about every site you've visited that has a FB like button. Also, separate from you and your data, FB has a tremendous graph of all the contacts, etc who have you as a contact. Collectively, this gives them a much greater reach and ability to make inferences than just what you directly share.
