This is a wild take. You can get chatbots to vomit out entire paragraphs of published works verbatim. There is functionally no mechanism to a chatbot other than looking at a bunch existing texts, picking one randomly, and copying the next word from it. There's no internal processing or logic that you could call creative, it's just sticking one Lego at a time onto a tower, and every Lego is someone's unpaid intellectual property.

There is no definition of plagiarism or copyright that LLMs don't bite extremely hard. They're just getting away with it because of the billions of dollars of capital pushing the tech. I am hypothetically very much for the complete abolition of copyright and free usage of information, but a) that means everyone can copy stuff freely, instead of just AI companies, and b) it first requires an actually functional society that provides for the needs of its citizens so they can have the time to do stuff like create art without needing to make a livable profit at it. And even if that were the case, I would still think the current implementation of AI is pretty shitty if it's burning the same ludicrous amounts of energy to do its parlor tricks.
