Introduction
Recent legal documents have exposed that Meta, the parent company of Facebook, allegedly used copyrighted materials to train its artificial intelligence (AI) models. According to court records, internal discussions among Meta employees raised concerns about utilizing unauthorized content, including pirated books, for AI development.

This revelation has sparked major debates about copyright laws, ethical AI practices, and the potential legal consequences for the tech giant.
Meta’s Alleged Use of Copyrighted Content
Court filings indicate that Meta employees downloaded an estimated 82 terabytes (TB) of copyrighted books without proper authorization. These materials were reportedly sourced to improve Meta’s AI models, but the practice raises serious legal and ethical questions. Some employees expressed concern, with one stating that “downloading from a corporate laptop doesn’t feel right.” This suggests that even within the company, there were doubts about the legality of the approach.
Mark Zuckerberg’s Involvement
The court documents further reveal that CEO Mark Zuckerberg was informed of these activities in early 2023. Despite warnings from Meta’s AI leadership about possible legal issues, reports suggest that Zuckerberg approved the use of this copyrighted content.

His decision has now become a central point in ongoing lawsuits, with plaintiffs arguing that Meta knowingly violated copyright laws to train its AI models.
Legal Battles and Copyright Infringement Lawsuits
Several prominent authors, including Sarah Silverman, Richard Kadrey, and Christopher Golden, have filed lawsuits against Meta. They claim that their copyrighted works were used without consent to train AI models such as LLaMA. The lawsuits argue that Meta’s actions constitute copyright infringement and unfair competition. If the courts rule in favor of the plaintiffs, Meta could face substantial financial penalties and be forced to change its AI training practices.
Meta’s Shift Away from Licensing Deals
Another major concern raised in the court documents is that Meta reportedly halted efforts to obtain licenses for books intended for AI training. Instead of securing proper rights, the company allegedly relied on unauthorized content, possibly to speed up AI development. This decision casts doubt on Meta’s commitment to ethical AI practices and compliance with intellectual property laws.
Talks of Libgen
Court documents also reveal that Meta employees considered using Libgen, an online repository known for providing access to copyrighted books without proper authorization. Internal discussions among Meta’s AI research team indicate that some employees viewed Libgen as a valuable resource for training data, despite its legal risks. One employee suggested that failing to use Libgen could place Meta at a competitive disadvantage in the AI race.

To minimize legal exposure, Meta staff reportedly discussed filtering out content explicitly marked as “stolen” or “pirated.” They also debated whether disclosing the use of Libgen would be necessary. Some employees argued that acquiring books through traditional licensing agreements would take too long and hinder AI model development. These revelations add another layer to the controversy surrounding Meta’s approach to AI training.
Impact on the AI Industry

The controversy surrounding Meta’s AI training practices is reshaping discussions on ethical AI development. Many experts argue that AI companies must ensure their models are trained on legally obtained and ethically sourced data.
The outcome of Meta’s legal battles could set a precedent for future AI research and the responsibilities of tech firms when handling copyrighted content.
Conclusion
The court filings highlighting Meta’s alleged use of copyrighted content for AI training have put the company under intense scrutiny. As AI technology evolves, companies must strike a balance between innovation and respecting intellectual property rights.

The legal outcomes of these cases will likely shape how AI companies approach data collection and copyright laws in the future.
