Zuckerberg recently announced that Facebook would emphasize user privacy more via encrypted messaging, a significant directional shift from the company's long-time goal of openness and connectedness. The change reflects Facebook's changing audience and continued problems with serving as a conduit for misinformation and vitriol.
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.
Cox's unexpected departure, which he and Zuckerberg announced in separate Facebook posts Thursday, comes months after Cox was promoted in a major reorganization. "My guess is there was some sort of disagreement".
Cox's departure removes a layer of management, bringing Zuckerberg closer to a family of apps that he wants to make compatible. "This place will forever be a part of me". Zuckerberg wrote that Cox considered leaving years ago to pursue new projects, but he chose to stay in 2016, around the time Facebook began taking heat for acting as a conduit for misinformation and Russian election interference.
Shares of Facebook were down 1.7 percent in extended trading following the announcement.
It is also interesting to see the head of WhatsApp Chris Daniels leaving Facebook right now. He was named the head of WhatsApp less than a year ago.
Facebook isn't hiring another executive to replace Cox. Chris Cox was responsible for Facebook's flagship apps - including WhatsApp, Instagram, and Facebook itself. In the past two years, the founders of Facebook acquisitions Instagram, WhatsApp, and Oculus have left for various reasons, often over strategy.
However, the latest exits are potentially more troubling, as Mr Cox and Mr Daniels were members of Mr Zuckerberg's tight-knit group of allies.
That effort will include introducing WhatsApp encryption technology to Facebook's Messenger app and Instagram's messaging option. In a note to employees about Cox's departure, Zuckerberg said Cox had been talking to him for a few years about doing something else but made a decision to stay after 2016 to help improve the social network. "Facebook Inc.is a massive and evolving company, so it's only natural that in a company that large, not everyone will agree with every strategic change", she said.
