A former Meta executive has sued the company in federal court in Northern California, claiming Meta attempted to “silence” her memoir, “Careless People.” The suit says a private arbitration order restricting her from discussing Meta or promoting the book is invalid and also argues that the severance agreement she signed includes a non-disparagement obligation that she signed under duress.

The plaintiff, Sarah Wynn-Williams—who served as Meta’s director of global public policy at Facebook from 2011 until she was fired in 2017—alleges that her book contains an explosive insider account of her experiences and includes claims about the conduct of Mark Zuckerberg and other executives. The lawsuit contends that Meta sought an emergency gag order and that, over time, company representatives monitored her public appearances, including by attending events and photographing her, to document alleged compliance with the restrictions.

The complaint also describes Meta’s position as that Wynn-Williams violated the agreement tied to the severance payment she accepted when leaving the company. Meta has said the book contains inaccuracies and that an arbitrator already ruled Wynn-Williams had broken the terms of the severance arrangement.

Wynn-Williams is asking the court to lift the arbitration order and vacate her severance agreement. She also claims Meta is seeking damages linked to alleged future breaches of the non-disparagement terms—an amount described in the lawsuit as $50,000 for each purported violation.
