Facebook CEO Mark Zuckerberg announced on Thursday that two top executives are leaving the company.
Chris Cox, Facebook’s top executive in charge of products, and Chris Daniels, the head of messaging service WhatsApp, will be departing for unspecified reasons, according to a blog post from Zuckerberg.
Cox, a Facebook veteran who has been a close adviser to Zuckerberg for years, decided to leave his role months after he was promoted to oversee all of the company’s apps, including Instagram, WhatsApp and Facebook Messenger.
“It is with great sadness I share with you that after thirteen years, I’ve decided to leave the company,” Cox wrote in a Facebook post.
Zuckerberg did not say why Daniels is leaving, but noted that he will be replaced by Will Cathcart, a vice president of product management who has been running the Facebook app.
The high-level departures come shortly after Zuckerberg announced that Facebook will be reorienting itself to become a more privacy-minded platform.
The company’s proposed “privacy-first” approach marks a radical shift in Facebook’s mission, reorienting from a focus on the platform’s public-facing News Feed feature — which Cox helped create — to its private messaging services.
The plan involves integrating Instagram Direct, WhatsApp and Facebook Messenger, allowing users to communicate across the different platforms.
Current and former employees told The New York Times that the decision to integrate the messaging services has caused some controversy and rifts internally.
