Five large book companies and writer Scott Turow have filed a lawsuit against Meta and Mark Zuckerberg. They say Meta took millions of protected books, textbooks, and articles from illegal websites including LibGen, Sci-Hub, and Anna’s Archive, then used this material to train its Llama AI models. The lawsuit claims Zuckerberg personally approved and encouraged the copying. It also says Meta removed or changed the copyright notices on the works. The companies argue this was planned large-scale theft, not just normal web scraping. They want the court to make Meta pay money and stop using their books. This is one of many lawsuits asking if AI companies can use protected material to train their systems without permission.
