I try to make my relatives understand that this is something important, to put forward rational arguments, but they refuse me, saying that it would only complicate their lives, so it’s useless. I’m seen as the paranoid of the gang. So how would you convince your friends?
Another angle is your contacts. Maybe you are clever enough to not be influenced by targeted ads but is everyone in your contact list? Many apps upload that data and obviously Facebook is using it in (arguably) good ways: “Do you know Emma?” (She just uploaded her contact list and you were on there)
