I'm not sure how to be upset over this. For decades copyright has been extended and extended. Meanwhile, the ease and speed of spreading published works across the globe have increased massively. Don't forget that when copyright was first created, it could take multiple years for first editions to make it across the globe. In that environment, multiple decades of copyright makes sense. Whereas today that would actually stifle innovation and creativity rather than incentivizing it. I mean, because of the length of copyright we've gotten all of these live action remakes of Disney films or superhero movies rehashing the same stories.

I find it a little hard to be upset about AI. Supposedly stealing copyrighted works when the vast majority of those works. Probably should have been in the public domain to begin with. I have a faint hope that this scuffle between the AI companies and the publishing industry will result in more reasonable copyright laws, but I think it's more likely that exceptions will be made and AI will be treated as a special case.
