This kind of program doesn't just suck up the data of the people who opted in with (theoretically) clear knowledge of what it means, it also likely pulls in data about the other people they communicate with using their phone, and none of those people consented to anything. Even if we were to pretend that isn't the case, why is it so necessary for companies to be able to suck up so much data about people? Why shouldn't we insist that companies respect our privacy in the same way we respect each others' privacy (I'm assuming that you don't go and peek into your neighbours' windows to figure out what they've been buying recently).
