Well, yeah, it is a jerk move! I also would be willing to bet that Facebook doesn't care. Just like they don't care about your privacy, beyond what they have to in order to avoid legal problems. Users are not really their customers, users are their products. They want to find every way possible to suck up information about you and make money off that. As long as people are angry but still using Facebook, I don't think anyone there will be loosing any sleep over this. Now if people actually started leaving in large numbers, they would take notice, because they would be loosing assets. Until there is a viable alternative, Facebook is going to keep doing things like this - count on it. As much as I hoped Google+ would be a viable alternative to Facebook so there would be a real reason for Facebook not to do things like this, it isn't there yet. I'm sure that you have already figured out that it is easy to change back, you just have to go in to your settings and change it back. After you catch it, of course.
