Not that expensive
I also think it's a very high price, but comparing to the latest major acquisition of the largest phone company here in Denmark, it may not been too bad; they paid 300$/customer to buy an upcoming mobile company, which was eroding their margins by aggressive pricing, thereby gaining customers fast.
I know an app is a different thing, but I'm pretty sure Facebook has done the math, and they know some people will abandon WhatsApp now.
They need to act to keep their user base high, also if that means expensive buying. And they mostly pay with their own shares, probably with a non-sell clause for some time.
