One of the things that has most amused me about creating https://www.thiswaifudoesnotexist.net is watching the reactions to images being posted elsewhere, especially without (initial) attribution: not a few people like the faces enough to request info about the character or artist, or say that it looks a bit machine-learning-like but is obviously too good to actually be ML-generated, or compliment OP on their illustration! People have begun casually using them as avatars, and there's one account on Pixiv for just uploading TWDNE or other faces generated by my StyleGAN models.

Even that has a spectrum, from "What is harry potter book is first?" to "What is the first line of harry potter?" to "What is the text of the first harry potter book?"
A lot of Google's answers to questions veer towards being written opinions and original definitions anyway
What's so interesting with ML is that there's a dense spectrum between memorization and originality. I hope in the future people start checking how much their models are memorizing.
My favorite case is Google's facts, like when you google "golden retriever weight." From other people going out, measuring it, writing it up, and publishing that info to the web, Google can extract the info and never direct traffic to those sites. I still don't know whether I think it's okay.
