My summary of the case: Someone did statistical analysis of a bunch of texts and created a tool that evaluates your text according to the developed model. Writers accused him of plagiarizing/using the content of their works.
I wonder if similar language exists in other copyright systems, but I would imagine it is likely the opposite...
Because one thing about the generative models is that you could in theory get the model to recite copyrighted work, word by word.
Only if it's so badly trained as to be considered broken. It's not fair or smart to judge an entire method (LLMs) by some broken examples. I wouldn't claim "all cars leak oil" just because I saw a broke-down beater one day.
