If people think Zuckerberg had "vision" doing this, I suppose I agree. But his vision wasn't "how can I help people have better online connections and experiences?" or anything like that. His vision was "how can I get people to share everything about their life, so Facebook can make more money?"

They are not one and the same thing, because in the latter, the priority is put on optimizing the experience for Facebook, not for the user.

Zuckerberg actually believes that there should be no privacy - at all. This is where he's leading Facebook. I believe that's a flawed vision, but he's probably sticking to it, because the less privacy you have, the more it helps the company.
