Mark Zuckerberg’s Presumed Successor Is Leaving Facebook

Mark Zuckerberg’s Presumed Successor Is Leaving Facebook

"It is with great sadness I share with you that after thirteen years, I've made a decision to leave the company", Cox wrote in his post. The company announced it's planning to shift its focus towards privacy and protecting users' information, something it has failed to do in recent times. "Since I was twenty-three, I've poured myself into these walls".

While Cox gave no specific reason for his move, he noted that Facebook chief Mark Zuckerberg has unveiled a new direction away from being the "digital town square" to focus on smaller-scale, private interactions.

Mr Cox was one of Facebook's first software developers and one of the chief architects of the news feed, the cascade of Facebook posts that is the company's most lucrative source of advertising.

Cox posted about his departure on Facebook, but didn't explain why he chose to leave.

In his blog post, Zuckerberg said that Cox had told him that he planned to move on several years ago, but that Cox chose to hold off on leaving until the company made more progress combating misinformation and Russian meddling - controversies that erupted in the wake of the 2016 election.


Zuckerberg, in a separate post, said Cox had discussed the possibility of moving on "for a few years", but had remained for a transition period. He is one of the most talented people I know and he has the potential to do anything he wants.

"As Mark has outlined, we are turning a new page in our product direction, focused on an encrypted, interoperable, messaging network", Cox wrote.

"Embarking on this new vision represents the start of a new chapter for us".

Also departing is WhatsApp Vice President Chris Daniels, adding to a string of recent high-profile exits from Facebook's product and communications teams. It isn't clear what future plans the executives have.

Daniels took the helm of WhatsApp after founders Jan Koum and Brian Acton left the messaging app a year ago, reportedly over disagreements about the increased integration of WhatsApp's operations with Facebook's.
