A coalition of about 35 local and regional newspaper publishers—representing nearly 400 titles—has filed a federal lawsuit against OpenAI and Microsoft, accusing the firms of copying copyrighted reporting to train ChatGPT, Copilot and other commercial AI products without permission or payment. The complaint alleges direct and vicarious copyright infringement, DMCA violations for removing notices and bylines, and seeks to protect financially strained local journalism that covers civic institutions. The case, the largest coordinated action by local news outlets, joins earlier suits by the New York Times, Alden Global Capital’s newspapers and MediaNews Group, highlighting a broader industry fight over who controls the raw material used to develop large language models. Plaintiffs argue the AI companies knowingly harvested their content, profiting from it while leaving newsrooms to bear the costs.
