In the wake of a Washington Post report that alleged a “clash” over Facebook data practices, WhatsApp co-founder and Facebook board member Jan Koum confirmed that he is leaving the company, effective immediately.
“It’s been almost a decade since Brian and I started WhatsApp, and it’s been an amazing journey with some of the best people,” Koum posted on his personal Facebook page on Monday. “But it is time for me to move on.” His status included a Facebook “emotional” tag indicating that he is “sad.”
Koum’s post doesn’t include an explanation of exactly why he’s leaving other than “doing things I enjoy outside of technology.” That leaves WaPo‘s Monday report as the loudest possible explanation available at the moment.
