WhatsApp co-founder quits Facebook, reportedly over privacy concerns
Jan Koum says he is taking time off to pursue interests; media accounts suggest clash over use of data led to his departure

WhatsApp co-founder Jan Koum on Monday announced that he is leaving Facebook, which bought the smartphone messaging service four years ago for $19 billion.
Koum, a Ukrainian Jewish immigrant to the United States, said in a post on his Facebook page that he is taking time off to pursue interests such as collecting air-cooled Porsches, working on cars and playing ultimate Frisbee.
US media reports indicated that a disagreement with Facebook over the privacy of user data may have also been a factor in Koum’s decision to quit his position as a high-ranking executive and likely leave his seat on the board at the leading online social network.
“It’s been almost a decade since Brian (Acton) and I started WhatsApp, and it’s been an amazing journey with some of the best people,” Koum said in the post.
“But it is time for me to move on.”
Acton left Facebook last year to start a nonprofit.
WhatsApp boasts more than 1.2 billion users worldwide. The encrypted messaging service does not run ads, whereas Facebook makes huge profits from its targeting advertising.
Koum spoke in 2014 of how his commitment to privacy stemmed from his childhood in Ukraine, and concerns that his family was spied upon by the KGB.
Facebook bought WhatsApp without ever devising a clear strategy for how that service would make money. Both Koum and WhatApp’s other co-founder, Brian Acton, had expressed an aversion to allowing ads into their service, causing analysts to wonder if the acquisition would ever pay off for Facebook.
In a reply to Koum’s post, Facebook co-founder and chief executive Mark Zuckerberg said he would miss working closely with the WhatsApp co-founder.

“I’m grateful for everything you’ve done to help connect the world, and for everything you’ve taught me, including about encryption and its ability to take power from centralized systems and put it back in people’s hands,” Zuckerberg said in his written reply.
“Those values will always be at the heart of WhatsApp.”
WhatsApp last week raised its minimum age for users in the European Union to 16 years, as the bloc prepares for a new online privacy law to come into force next month.
In an update to its terms of service, WhatsApp said the minimum age for users outside the EU was still 13 years.
WhatsApp’s parent company Facebook has pledged to change how it handles private data to comply with the forthcoming law change.
But unlike WhatsApp, which will only apply the new law to its European users, Facebook plans on rolling out changes for its users worldwide.
The change in the European law was already planned prior to the recent privacy scandal involving Facebook and Cambridge Analytica.
Zuckerberg has spent most of the past month on the fallout from revelations on the hijacking of personal data by the political firm, seeking to assuage fears that the California-based internet colossus can safeguard privacy while making money by targeting ads based on what people share about themselves.
