I used to think that Facebook maybe cared about its users, but sometimes had an experiment go wrong. Or they were maybe going to change the game so the whole world cared less about privacy, and maybe this would help society or something.
I feel sorry for Facebook, really; they're in a new industry where it's not clear what you can and can't do, and if you step over the line, the whole internet blasts you. Furthermore, with so much data about everyone, there are all these cool things you could do if people would let you, but to do them, you have to get people's permission. And more permissions for more things -> more complexity.
But maybe they should just quit while they're ahead. Today, Facebook haters, I stand with you. To try to use Facebook without accidentally making huge privacy errors is too much of a headache. And if Facebook actually cared about its users, it would take much bigger steps to make sure this situation didn't happen. I'm not deleting my account, because it's useful for its basic purpose (remembering people's email addresses and stuff), but I'm sure not going to be adding more information there.
