Elsevier Inc., Cengage Learning, Hachette Book Group, Macmillan Publishers, McGraw Hill LLC, and Scott Turow v. Meta Platforms, Inc. and Mark Zuckerberg
Five major publishers (Elsevier, Cengage, Hachette, Macmillan, McGraw Hill) and author Scott Turow filed a putative class action accusing Meta of pirating millions of books and journal articles to train its Llama models without permission or payment. The complaint alleges Meta abandoned licensing talks in 2023 and deliberately relied on shadow libraries, and that Llama can reproduce full scientific papers, textbook chapters and study guides that substitute for the plaintiffs’ own products.
