Long-time Facebook executive Chris Cox on Thursday announced his return to the social media company, saying he will resume his role as chief product officer.

“Facebook and our products have never been more relevant to our future,” Cox wrote on his Facebook page. “It’s the place I know best, it’s a place I’ve helped to build, and it’s the best place for me to roll up my sleeves and dig in to help.”

Cox returns to the company after suddenly quitting in March 2019 after a decision by CEO Mark Zuckerberg to pivot the company toward privacy and encrypt the private messages sent between users on Messenger, WhatsApp and Instagram. Critics have said that the encryption of these messages will make it harder for Facebook to monitor and prevent child exploitation through its services. 

“I’m really excited Chris is coming back to Facebook,” Zuckerberg wrote in a post

Cox has previously been described by employees as the heart and soul of Facebook, playing a major role in welcoming employees when they first join the company. Cox said his return will be June 22, and he will attend the company’s Q&A on Thursday to answer questions.

“I’ve been following Facebook and I’ve been encouraged by progress on so many of the big issues facing us,” Cox wrote. “In the past month the world has grown more chaotic and unstable, which has only given me more resolve to help out.”

A number of employees took to Twitter to praise Cox’s return.
