"Mr. Stamos, who plans to leave Facebook by August, had advocated more disclosure around Russian interference of the platform and some restructuring to better address the issues, but was met with resistance by colleagues, said the current and former employees. In December, Mr. Stamos’s day-to-day responsibilities were reassigned to others, they said.

Mr. Stamos said he would leave Facebook but was persuaded to stay through August to oversee the transition of his responsibilities and because executives thought his departure would look bad, the people said. He has been overseeing the transfer of his security team to Facebook’s product and infrastructure divisions. His group, which once had 120 people, now has three, the current and former employees said."
