If I said, “I’m going to come by your house, survey all of your personal data, rifle through your files, and share some parts of what I’ve learned with whomever pays me the most money, under terms that can change at any time to be even more in my favor,” you’d kick me out without even thinking twice. If I said, “But wait! If you let me do this, I’ll reintroduce you to people you hated in high school, and let you play with virtual farm animals!” you’d probably be beating me while I was on the way out. But that’s the exchange we make with Facebook every day.
