His last day at Facebook will be 17 August. “It is critical that we as an industry live up to our collective responsibility to consider the impact of what we build, and I look forward to continued collaboration and partnership with the security and safety teams at Facebook,” he noted. Inside Facebook, Stamos had been strongly advocating for investigating and disclosing Russian activity on the social media platform. Facebook’s reputation is already under attack over Russia’s alleged use of Facebook tools to sway US voters with divisive and false news posts before and after the 2016 election. According to The Verge, Stamos, who joined Facebook in 2015, won’t be replaced after he leaves, “meaning no one will hold the title of ‘Chief Security Officer’ at Facebook”. Facebook chief operating officer Sheryl Sandberg said that the company “looks forward to collaborating with him in his new role”.
