The problem is that these "small things" are not necessarily small if you're an individual.

If you're an individual pirating software or media, then from the rights owners' perspective, the most rational thing to do is to make an example of you. It doesn't happen everyday, but it does happen and it can destroy lives.

If you're a corporation doing the same, the calculation is different. If you're small but growing, future revenues are worth more than the money that can be extracted out of you right now, so you might get a legal nastygram with an offer of a reasonable payment to bring you into compliance. And if you're already big enough to be scary, litigation might be just too expensive to the other side even if you answer the letter with "lol, get lost".

Even in the worst case - if Anthropic loses and the company is fined or even shuttered (unlikely) - the people who participated in it are not going to be personally liable and they've in all likelihood already profited immensely.
