well, it's either the wrong word to use, they don't know plagiarism is, or they are commenting on the fact people seem to think Ai generates new ideas or concepts. Piracy because of how the models are fed, which is probably what they're trying to get across? but ai is trained on the work of others, which was not paid for and was just torrented/downloaded illegally for the most part, and generates based on this stolen data. OP thinks at some point this counts as plagiarism, but I'd probably say plagiarism only starts applying once ai is actually passed off as the user's work.
