I haven't seen that movie, but let me just say that I simply can't help but deeply mistrust a person who considers privacy "obsolete" (which he has stated multiple times in the past) and, through his creation, effectively works to reduce it for everybody.

I'm deeply scared of a future where you need a Facebook (and/or Google) account to do anything meaningful on the web, and I hope that we will never arrive at such a future. I won't join Facebook under any circumstance short of a gun pointed at my head.
