LLM outputs are not copyrightable or rather the user who generated them owns it.

That entirely settles it and there isn’t much else to say about.

If Anthropic feels that other countries are violating their EULA well they are free to stop doing business with them.

The claim these companies make goes much, much further than that.

They claim LLMs "uncopyright" their inputs. So if I take, say, 50 Mickey Mouse comic books, tell ChatGPT to read them and produce 50 "Buster Beagle" comic books that there is ZERO "copyright contamination" and I own those 50 output comics without Disney having any claims on them whatsoever.

Or if I ask ChatGPT to "make a spreadsheet software like Excel, Sheets, Calc, ..." that, again, there is zero copyright claim possible from these people.

It has not been tested, of course.
