To anyone who is reading this comment without reading through the article. This ruling doesn't mean that it's okay to pirate for building a model. Anthropic will still need to go through trial for that:
But he rejected Anthropic's request to dismiss the case, ruling the firm would have to stand trial over its use of pirated copies to build its library of material.
As a civil matter, the publishing houses are more likely to get the full money if anthropic stays in business (and does well). So it might be bad, but I'm really skeptical about bankruptcy (and I'm not hearing anyone seriously floating it?)
It might be that bad. Most 'damage' (as publishers see it) comes from distribution, not the download itself. Depending on how they acquired the books, it might be not be much of a problem.
