In his new book, due out next month, Facebook investor Roger McNamee reiterates his claims that the social network is bad for society while also offering fresh details on his efforts to bring regulatory attention to the company.

Why it matters: McNamee’s status as a one-time adviser to Facebook founder Mark Zuckerberg has made him one of the company’s most prominent critics. But Facebook is pushing back: “The reality is Roger McNamee hasn’t been involved with Facebook for a decade,” said a spokesperson.

• He is critical of Zuckerberg and COO Sheryl Sandberg in the book, which is excerpted in the new issue of Time magazine and featured on the cover.
• He says that when he once talked to Sandberg about “a failure of judgment that in most companies would have resulted in the termination of the person who made the decision and changes in policy,” she at one point said: “Are you saying you want me to fire the entire team?”
