This is kinda my take on it. However, the way I see it is that the AI isn't intelligent enough yet to truly create something original. As such, right now AI is closer to being a tool than a being. Because of that, it somewhat bothers me that I'm being used to teach a tool. If I thought that companies like OpenAI were truly trying to create beings and not tools, then I'd feel differently.

It's kinda nuanced, but a being can voluntarily determine whether or not something is copyright infringing, understand why that might be an issue, and then decide whether or not to continue writing based on that. A tool can't really do that. You can try and add filters to a tool to avoid writing copy written text, but that will have flaws and holes in it. A being who understands what it's writing and what makes it plagiarism vs reference vs homage/inspiration/whatever is less likely to have those issues.
