Five publishers sue Meta over unauthorized Llama training data

The suit adds publishers and a marquee author name to the mounting copyright litigation over AI training data. Five publishers plus novelist Scott Turow allege Meta ingested millions of copyrighted books and academic articles without permission or licensing to train Llama, and they're seeking both substantial monetary damages and an injunction to halt further alleged infringement — notably including the destruction of unauthorized copies of the protected works.

Meta's defense rests on fair use, the same argument other labs have advanced, and the case will test how courts weigh transformative-use claims against wholesale ingestion of copyrighted corpora. The 'destruction of copies' demand is significant because it targets the training data itself, not just outputs — a remedy that, if granted, would be far more disruptive than damages. The theme even surfaced in community discussion via an r/Anthropic thread referencing 'Project Panama' and book destruction.

Contextually, the timing is pointed: Meta is simultaneously pivoting to a closed, paid Muse Spark API, so its legal exposure on the open Llama models it built on contested data intersects with a strategic shift away from them. What to watch: whether the class is certified, how the court treats the fair-use defense relative to prior AI-training rulings, and whether the injunction/destruction remedy gains any traction.
