Of course the things you're suggesting will allow Facebook to add features to the product, and indirectly perhaps add revenue.

That is very different from this: "The only way they can do it is by selling users data one way or another.". People often claim that Facebook wants to "sell" your data to advertisers, and I'm simply saying that claim is wrong.

(I've never been secretive about the fact that I worked at Facebook, it's on my profile. )

The problem here is that FB makes more money by making user profiles more public. They have shown it already. And, I doubt you will disagree with me on this fact.

Now, you can argue that making private information public to generate revenues is not selling, however, IMO, it is, given the fact that they started out as a completely private social network.
