Facebook's product chief Chris Cox and WhatsApp's head of messenger service Chris Daniels leave the group. This emerges from a message from Facebook CEO Mark Zuckerberg to his employees. Cox and Daniels had decided to leave, wrote Zuckerberg. He has been discussing this with Cox for several years.

Cox started working for Facebook in 2005 as one of 15 software engineers, building the so-called newsfeed. A direct successor to him was not named. Daniels headed WhatsApp after founders Jan Koum and Brian Acton left the company. His successor will Will Cathcart, who was previously responsible for the operation of the Facebook app. Facebook took over WhatsApp in 2014.

Last week, Zuckerberg announced that in the future, Facebook would focus less on public posts and more on private conversations - a shift from the "digital marketplace" to the "digital living room". WhatsApp, Facebook's Messenger and Instagram, which also belongs to the Facebook group since 2012, would be linked to each other. According to the New York Times , this measure was rejected by several employees.

With two billion users, Facebook is the largest social network in the world. Again and again, the company comes because of privacy concerns in the criticism. In March 2018, it was announced that the analytics company Cambridge Analytica is said to have illegally acquired the data of millions of Facebook profiles in order to influence the US presidential campaign in favor of Donald Trump. As a result, Zuckerberg acknowledged mistakes, including at a hearing in the European Parliament.
