Unsealed Briefs in Authors’ Case v. Microsoft/OpenAI: Top Execs Knew Their Mass Book Piracy Was Illegal And Would Put Authors Out of Work

The Authors Guild — September 21, 2026

Explosive new documents released in Authors Guild v. OpenAI — the major book authors’ ongoing lawsuit alleging OpenAI and Microsoft illegally trained their products on copyrighted books — show that executives and employees at both companies intentionally broke the law and expressed disdain for human authorship.

Plaintiffs include The Authors Guild and writers including David Baldacci, Taylor Branch, Michael Connelly, Sylvia Day, Jonathan Franzen, John Grisham, George R.R. Martin, Jodi Picoult, and others. Authors Guild CEO Mary Rasenberger: filings reveal “repeated, intentional decisions to steal books rather than pay for them with full knowledge that their products will destroy the careers of authors.”
