Number 4 means you don't have to use the service at all, and no one is forcing you.

The only reason I use Whatsapp is for contacts that don't have Skype (even your fancy Facebook is too new and webby for me).

Video calls are a must for me, but they seem to be a thing of the past now.

Of course nobody is forcing me, it just boggles my mind that they have any market share at all. It feels like watching a six year old randomly throw paint at a canvas and selling it at auction for $50 million.

What boggles my mind is that MS could have it all but simply neglected Messenger until it died.

WhatsApp success is built more on MS failure than anything else.
