Repeating my comments from the previous thread which was deleted for some reason:

Why would people be OK with constant security risk, but not OK with one time registration step for normal XMPP service? XMPP clients are available for all major desktop and mobile platforms. So it's a really interesting psychological hook that Whatsapp developers catch their users on here, offering a completely inferior solution, with selling it of for the fake attraction. And it's a really nasty thing to do - to play on people's ignorance regarding security.

So why would Facebook want to buy this monstrosity? The only valid reason could be to convert it to proper XMPP, then I'd applaud them, but on the other hand Facebook's own IM service isn't federated, which defeats the purpose. So it doesn't look like it can improve Whatsapp in any way.
