Does anyone know the founders' employment history before Whatsapp? Have any of them been a part of a buyout or merger before?

I empathize with Jan & I think he believes what he has written, but does he think Facebook bought them for no reason at all? If he wants us to take him seriously he should explain how Whatsapp intends to make money for Facebook. Even implementing OTR won't totally protect users' privacy, so long as a megacorp is capable of performing traffic analysis.
