I am. The only remotely valuable data WhatsApp makes available to Facebook is contact lists, and frankly they already have all that data.

WhatsApp is definitely losing them money, but it's obviously more than worth a small loss to have control over the messaging system that most of the world uses. Facebook doesn't want Google or whoever to get a popular social app and leverage that to move into spaces that Facebook actually makes money.

So I guess in a sense you could way we're indirectly paying for it via Facebook ads (if you actually use Facebook).
