No, that’s literally why Anthropic got sued. If they’d paid for a copy of the copyrighted works they pirated, they wouldn’t have had a problem. There were two issues in their case: does the AI infringe on copyright and did Anthropic obtain all their materials legally. The first they won on, the second they lost.

So if you pirate a bunch of content you still get in trouble for that. But if you somehow make a business out of that that isn’t just redistributing those materials, then that business itself isn’t infringing.
