Read the comments you're replying to. I didn't comment on the legality of ChatGPT training on my content, I said I didn't like it. Regardless, the act of posting content publicly does not mean I give up my copyright claim. Yes, there are fair use situations. Training ChatGPT might be one of them, but I'm not seeing lot of concrete information one way or the other and I am seeing arguments that ChatGPT could be considered a derivative work, which would place OpenAI in violation of my copyright.

Send some links if you see some definitive case law sorting this stuff out.
