A 57-page complaint filed to a US district court in California on Thursday argues that an interim arbitration ruling sought by Meta preventing Wynn-Williams from publicising her memoir, Careless People, was “improper and unlawful” and a “blatant violation of the first amendment”. It also accuses the company of “coercive surveillance”. Wynn-Williams, who between 2011 and 2018 served as director of global public policy at Facebook, published her memoir of her time at the company in March 2025 . The book contained allegations of a toxic internal culture, including sexual harassment and gender-based discriminatory practices. The company has described the book as a “mix of out-of-date and previously reported claims about the company and false accusations about our executives”. Upon publication, Meta sought an emergency order preventing Wynn-Williams from promoting the book, on the basis that she had signed a severance agreement that included arbitration and non-disparagement clauses. Thursday’s complaint, accompanied by a 285-page declaration by Wynn-Williams, argues that the severance agreement is unenforceable partly because it was signed under financial duress. It says when Facebook fired Wynn-Williams in August 2017, the company knew her termination would take away “critical employment benefits” – described as “cornerstones of her financial stability” – meaning she “had no choice” but to accept the severance agreement, allowing her to retain many of the benefits and obtain a significant cash payment. In late May, Wynn-Williams appeared at Hay literary festival in Wales alongside the journalist Carole Cadwalladr and the academic Tim Wu but she did not speak , based on legal advice. Despite this, Meta wrote to the merits arbitrator on 12 June to request that it impose additional sanctions based on her appearance, the complaint reveals.
