Facebook's users do not profit. They provide labor to improve the value of facebook with no compensation in return, so the relationship is unbalanced. I think this is demonstrably false. It's true, my brother doesn't get paid by Facebook to spend time on the site. Google doesn't pay me to use GMail either, and yet I use it every day all day. Money isn't the only way to provide value. And there's no way Facebook could have reached 400 million users without providing value to a lot of those people.
