WhatsApp CEO and co-founder Jan Koum has confirmed that he is leaving the company. According to reports, the move has come after Koum clashed with parent organisation Face Book over its approach to WhatsApp strategy, encryption and its attempt to collect user's personal data. Koum took to Facebook and posted comments in which he said it's been an amazing journey with some of the best people. But it is time for me to move on. It is yet to be known when he is going to leave the organisation.
