While I share your general suspicion I don't think they need to see the messages to get a lot of privacy-violating use out of WhatsApp.
When the NSA was talking about metadata collection, they said it was more useful than actual data. Likely because it's already computer consumable, and less dense.
If FB gets your contact lists, and sees who you message, how much, and when, that's probably a hugely valuable commodity to them.
