I wasn't referring to whether the LLM commits copyright infringement when creating a text (though that's an interesting topic as well), but rather the act of feeding it the texts. My point was that it is not like us in a sense that we read and draw inspiration from it. It's just taking texts and digesting them. And also, from a privacy standpoint, I feel kind of disgusted at the thought of LLMs having used comments such as these ones (not exactly these, but you get it), for this purpose as well, without any sort of permission on our part.
That's mainly my issue, the fact that they have done so the usual capitalistic way: it's easier to ask for forgiveness than to ask for permission.
