Summary

Court records in an ongoing lawsuit reveal that Meta staff allegedly downloaded 81.7TB of pirated books from shadow libraries like Z-Library and LibGen to train its AI models.

Internal messages show employees raising ethical concerns, with one saying, “Torrenting from a corporate laptop doesn’t feel right.”

Meta reportedly took steps to hide the activity.

The case is part of a broader debate on AI data sourcing, with similar lawsuits against OpenAI and Nvidia.
