I was toying around with your (quite excellent) Yowsup library a little while ago and the one question I always had was this: Since WhatsApp doesn't have an official library, wasn't Yowsup always in the cross-hairs?

I mean, it was only a matter of time before they clamped down and claimed that you were violating section 3.A.iii of the ToS by reverse-engineering the WhatsApp protocol, right?

Don't get me wrong, I would have loved it if Yowsup was allowed as an (unofficial) API - or something like that. However, as a newbie to the world of programming & software development in general, I am trying to understand what was wrong about the DMCA notice. What, in your opinion, should they have done instead?
