An attorney who previously represented Meta as a client has dropped the social media giant amid growing frustrations over the company’s recent changes.

Mark Lemley, a Bay Area intellectual property attorney and Stanford Law School professor, had represented Meta in a proceeding over the company’s alleged use of copyright texts for training artificial intelligence. The case, brought by a group of authors, could lead to precedent case law.

But Lemley couldn’t rationalize what he called “Facebook’s descent into toxic masculinity and Neo-Nazi madness,” he wrote on Bluesky.

On Monday, the attorney had been removed from the case and Meta’s roster. While Lemley believed his client was on the right side of the case, he said: “I cannot in good conscience serve as their lawyer any longer.”
