I have 3 (!) groups that haven't moved because of 1 person out of 5 or so that refuses and has a "I have nothing to hide, I don't mind targeted ads."-attitude (and tbh a majority of people that care just a little bit). The network effect is strong. It's annoying. I ask them to use another (almost exact copy of an) app, they ask me to share my address book (among others) with FaceBook (probably also among others).
