Yowza. Here's a 2009 BBC interview with Mark Zuckerberg, with an excerpt below.
Reporter: So who is going to own the Facebook content, the person who puts it there, or you?
Zuckerberg: The person who puts the content on Facebook always owns the information, and this is why Facebook is such a special service.
Reporter: And you won't sell it?
Zuckerberg: No, of course not.
Reporter: Just to be clear, you're not going to sell, or share, any of the information on Facebook?
Zuckerberg: We're not going to share people's information except for with the people that they've asked for it to be shared.
