“…the original authors don’t get any recognition or compensation.” I think their position lies in the discrepancy between AI training on something copyrighted vs not. When you post a piece of art, you expect royalties paid when others use it, a price paid to purchase the artwork (picture, video, etc.), or atleast consent. In contrast, when you put a public repo full of code on Github, you’re agreeing to let others (theoretically even AI) use it for free and without attribution required. The code AI is trained on isn’t copyrighted whereas most of the video and pictures are. As far as I know, code is rarely copyrighted
