Ya well, what I said before. After WhatsApp tighten security with end to end encryption by default, there seems to be only one reason for the rant from Threema against WhatsApp. Their business model just got busted. There is no advantage of Threema left, while WhatsApp has millions and millions users. Chances are people are now not even bothering anymore for paying to Threema when all of their contacts already use WhatsApp. Well most of them didn't care before anyway. And now they all use end 2 end encryption. That makes it a good thing.
