There's a few efforts at full open data / open weight / open code models, but none of them have gotten to leading-edge performance.
If you (or any human) violate copyright law, legal redress can be sought. The amount of damage you can do is limited because there's only one of you vs the marginal cost of duplicating AI instances.
There are many other differences between humans and AI in terms of capabilities and motivations to f the legal persons making decisions.
Assume for a moment, that the current AI is teaching us that compute transforming data → information → knowledge → intelligence → agency → ... → AGI → ASI, is all there is to Intelligence-on-Tap? And imagine an AI path opens to AGI now and ASI later, where previously we didn't see any. Seems a bad deal to me, to frustrate, slow down, or even forego the 2050-s Intelligence Revolution that may multiply total human wealth by a factor of 10 to 20 in value, the way the Industrial Revolution did in the 1800-s. And we are to forego this, for what - so that we provide UBI to Disney shareholders? Every one of us is richer, better off now, than any king of old. Not too long ago, even the most powerful person in the lands could not prevent their 17 miscarriages/stillbirths/child_deaths failing to produce an heir to ascend the throne (a top priority that was, for sure for a king+queen). So in our imagined utopia, even the Disney shareholders are better off than they would be otherwise.
But enough about whether it should be legal to own a Xerox machine. It's what you do with the machine that matters.
However, once these words are broadcast—once they’re read, and the ideas expressed here enter someone else’s mind—I believe it’s only fair that the person on the receiving end has the right to use, replicate, or create something from them. After all, they lent me their brain—ideas that originated in my mind now live in theirs.
This uses up their mental "meat space," their blood sugar, and their oxygen—resources they provide. So, they have rights too: the right to do as they please with those ideas, including creating any and all data derived from them. Denying them that right feels churlish, as if it isn’t the most natural thing in the world.
(Before people jump on me:- Yes, creators need to be compensated—they deserve to make a living from their work. But this doesn’t extend to their grandchildren. Copyright laws should incentivize creation, not provide luxury for the descendants of the original creator a century later.)
Copyright isn’t violated when someone consumes a copyrighted work.
Copyright is violated when a copyrighted work is used by someone who isn’t the author to generate profit without prior permission.
You can read a copyrighted book and remember it. You cannot copy it and sell copies. If you want to excerpt it you must give credit and there are limits to what’s considered “fair use”.
