Seeing this and being surprised is like watching a teen movie where the gossiper invites the entire school to listen in on the phone line while the protagonist is (unwisely) sharing a secret with them, and thinking as you watch, "that's totally out of character for the gossiper - even though they want to collect people's information themselves, there's no way they would invite other people to listen in as they're in the process of receiving that information." Doesn’t that depend on who’s surprised? My parents would be shocked by this, people working in the software industry should be less shocked. I bet that a poll of 100 randomly selected people asking, “What does documentation mean in the context of software?” would discover that few knew the answer. Never mind actually reading the docs, or understanding their implications. Facebook goes to some trouble to ensure that only a small minority of people grasp the implications of how they’re monetizing their users.
