Will be interesting to see if they see this through. I might be missing something, but I don't see any business reason for them to do this. They will lose some users, and that seems a painful prospect for them. They value user bases so much that they paid $19B for Whatsapp.

Difficult to imagine them not reversing this decision at a later date.

Their purchase of whatsapp is exactly why they did this, IMO. I'd be very surprised if facebook messages doesn't become whatsapp and get completely tied into it. That's really the only way buying WhatsApp for $19B makes sense.
