Sony and Warner sued Anthropic over torrenting, and named two founders personally

Sony Music Publishing and Warner Chappell filed August 28 in the Northern District of California against Anthropic, CEO Dario Amodei and co-founder Benjamin Mann, over what they call a "brazen campaign of illegally torrenting, scraping and downloading copyrighted works on a massive scale."

Damages sought run to $150,000 per infringed work plus $25,000 for each instance of stripped copyright management information, across tens of thousands of compositions. Named works include "Eye of the Tiger," "All I Want for Christmas Is You," "Hallelujah" and Taylor Swift's "Paper Rings." Four counts, and contributory infringement is pleaded against the two founders as individuals. (Music Business Worldwide)

Two things separate this from the 2023 lyrics suit. That one was about model output, whether Claude reproducing lyrics infringes. This one targets acquisition, whether obtaining the training corpus by torrent was itself unlawful regardless of what the model does with it. Fair use arguments about transformative output don't reach that question. Downloading from a torrent swarm also means uploading, and distribution is a different claim than copying.

The second is the personal naming. Suing founders individually for contributory infringement is a pressure tactic and it's also a signal about how the plaintiffs read the internal record. You don't plead that without believing you'll find someone's name on a decision.

I have no prediction on the outcome and neither does anyone else honestly. What I'd think about as a builder: if you embedded Claude in something you're selling this month, you have a procurement exposure that has nothing to do with your code. Enterprise buyers with a legal function will ask about model provenance in the next RFP cycle if they weren't already, and "our vendor is in litigation over how the weights were trained" is a real line item now.

The narrower version of that risk showed up in adoption data this week. Jamin Ball argues in Clouded Judgement that architectural deletion of prompts and responses now beats retention policy, because policy can be amended and deletion can't. When Anthropic released Fable 5 with 30-day retention instead of zero data retention, Microsoft restricted employee access and GitHub disabled it by default, and adoption trailed the cheaper Opus 5 despite Fable 5 at $10 per million input tokens against GPT-5.6's roughly $5.

Price wasn't the blocker. Data handling was. Same shape of concern as the lawsuit, different end of the pipe.
