"The billionaire chief executive of WhatsApp, Jan Koum, is planning to leave the company after clashing with its parent, Facebook, over the popular messaging service’s strategy and Facebook’s attempts to use its personal data and weaken its encryption, according to people familiar with internal discussions."
The other WhatsApp founder who already left Facebook, Brian Acton, gave $50 million to start the Signal Foundation with Moxie Marlinspike, and is part of the #DeleteFacebook campaign. Facebook must hate these guys.
