Jan Koum's announcement to leave the company's management comes after he recently contradicted Facebook's leadership over what Strategy will adopt in the future. He has resisted Facebook's use of user's personal data and weakening encryption methods used by the application, Washington Post reported.
"It's been nearly a decade since we started with Brian Acton, WhatsApp, and it's been a great trip with some of the best people, but it's time for me to move on," Koum said in a post on its Facebook page
He did not give a concrete date for leaving the company and could not be contacted to comment, Reuters quotes
Facebook's chief executive, Mark Zuckerberg, commented on Koum's post, saying he is grateful for what he taught him about encryption and "his ability to take power from centralized systems and put them back into the hands of men."
