It sounds like you need to take a moment to consciously reflect on the fact that not everyone cares about privacy to the same extent you do. I don't just mean the privacy of others, but their own privacy as well. To many people, the loss of privacy that comes from being searchable is more than offset by the value they get out of Facebook.

I think it's more that most of the users are ignorant of the privacy implications.
