Meet Sarah Wynn-Williams, Facebook’s Highest-Ranking Whistleblower

You may have never heard of Sarah Wynn-Williams, but that’s about to change.

She’s written a memoir about her nearly seven years at Facebook, the company that has since rebranded as Meta. In doing so, she’s become the company’s highest-ranking whistleblower.

Until around 72 hours ago, the book’s existence itself was a secret. Wynn-Williams, a onetime New Zealand diplomat, was effectively the company’s top envoy to governments around the world. She traveled extensively with Mark Zuckerberg and Sheryl Sandberg—the company’s two top leaders during her time—and her experiences with them often read like pure comedy, a mix of Succession and The Office.

The book, however, is a lot more than that. It’s a shocking insider’s account of working at one of the world’s most powerful companies at the highest level, and the gap between the idealistic way it sold itself to its employees and the world.

It’s called "Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism." And it coincides with the news that Wynn-Williams has filed an SEC complaint against the company, alleging that Zuckerberg agreed to crack down on the account of a high-profile Chinese dissident living in the U.S. in the hopes that it would help convince Beijing to allow Facebook into China.

On today’s Honestly, Bari and Wynn-Williams discuss her bizarre experiences, her thoughts on the future of Facebook, the pushback she’s already received, and why she wrote this book—despite the risk of taking on a corporate behemoth like Meta.
