For well over ten years now, companies like Facebook/Meta and Google have perused research code by academic and other researchers, seen what is catching on, then soon made better versions themselves. Google in particular has soon also offered commercial services for the same, outcompeting the smaller commercial services offered by the researchers. Frankly, I am glad Google does it because the world is better for it. It's the same with Amazon because frankly it's a lot of work to scale a service globally, and most smaller groups would do a far worse job at it.
My criteria for what is good vs bad is what makes the world better or worse as a whole, not what makes me better off. It is clear to me that the availability of AI triggered by GPT has made the world better, and if OpenAI has to violate copyrights to get there or stay there, that's a worthwhile sacrifice imho. There is still plenty of commercial scientific and media writing that is not going away even if copyright laws were to disappear.
Book readership (outside of school) is already very low now, and is only going to get lower, close to zero. You might be defending a losing field. An AI is going to be able to write a custom book (or parts of it) on demand - do you see how this changes things?
Ultimately I realize that we have to put food on the table, but I don't think copyrights are necessary for it. There are plenty of other ways to make money.
