Yes. And from the article "That Anthropic later bought a copy of a book it earlier stole off the internet will not absolve it of liability for theft but it may affect the extent of statutory damages." Sounds reasonable (except for the "stole" and "theft" language -- a copyright violation is a copyright violation, not theft, not stealing).

If the actual model was trained from the unauthorized copies, and then they post-hoc bought the books, that doesn't retroactively cancel the initial copyright violation. As I understand they did not retrain the model using the OCR'd scans
