The head of popular messaging service WhatsApp is planning to leave the company because of a reported disagreement over how parent company Facebook is using customers' personal data.
WhatsApp billionaire chief executive Jan Koum wrote in a Facebook post Monday, “It's been almost a decade since (co-founder) Brian (Acton) and I started WhatsApp, and it’s been an amazing journey with some of the best people. But it is time for me to move on,” he said.
Koum did not give a date for his departure.
The Washington Post reported Monday that Koum is stepping down because of disagreements over Facebook’s attempts to use the personal data of WhatsApp customers, as well as efforts to weaken the app’s encryption.
Action left the company last fall and since then has become a vocal critic of Facebook, recently endorsing a #DeleteFacebook social media campaign.
The Post, citing people familiar with internal WhatsApp discussions, said Koum was worn down by the differences in approach to privacy and security between WhatsApp and Facebook.
When WhatsApp agreed to the company’s sale to Facebook in 2014 for $19 billion, it said WhatsApp would remain an independent service and would not share its data with Facebook.
However, 18 months later, Facebook pushed WhatsApp to change its terms of service to give the social network access to the personal data of WhatsApp users.
WhatsApp is the largest messaging service in the world with 1.5 billion monthly users. However, Facebook has been struggling to find ways to make enough money from the app to prove its investment was worth the cost.
Facebook has faced intense criticism since March when news broke that the personal data of millions of Facebook users had been harvested without their knowledge by Cambridge Analytica, a British voter profiling company that U.S. President Donald Trump's campaign hired to target likely supporters in 2016.
Facebook chief executive Mark Zuckerberg testified before Congress earlier this month and apologized for inadequately protecting the data of millions of social media platform users.
Facebook also recently announced it would allow all its users to shut off third-party access to their apps and said it would set up “firewalls” to ensure users’ data was not unwittingly transmitted by others in their social network.
Some members of Congress said Facebook’s actions to rectify the situation did not go far enough and have called for greater regulation of the internet and social media.
