I thought one of the main things about Whatsapp was the huge audience and the demographics of that audience skewed young, and this app while not quite the install base size of Whatsapp/Instagram is ppoular with young folks. The demographics is the one they teach in Psych 101 as the most crucial point at which marketing can influence lifelong brand choices. The tweet snark seems to miss the point altogether.

Did they? I remember people balking at the price of Whatsapp but not the actual of buying it, it was widely seen as a huge benefit to Facebook.
