End of the road for major AI companies, and hopefully something better can be created once it's declared illegal without any murky waters.
There are LLMs trained on data that isn't illegally obtained, OLMo by Ai2 is one such model, that is actually open source and uses open data for training. Just because it's "very difficult" for OpenAI et al shouldn't be an argument to force them to behave ethically anyways. If they cannot survive acting legally, then so be it, sucks for them.
