Meta is alleged to have unlawfully used pirated books for training its AI models, downloading at least 81.7 terabytes of data from torrent sources, including 35.7 terabytes from Z-Library. Internal communications reveal employee concerns about the legality of downloading pirated content, while leadership reportedly obscured their activities and operated in "stealth mode." Plaintiffs are seeking renewed interrogations of Meta personnel, claiming previous testimonies were misleading, and asserting that Meta's copyright infringements may involve distribution of pirated books. Meta defends its actions as falling under "fair use" and intends to challenge the allegations. Additionally, Meta and its products are prohibited in the Russian Federation due to being designated as extremist.
