@dajb @cwebber @davidrevoy I'd think it would be easier to start with CC BY-ND and then add an exception to allow for derivatives if they were not AI.
However, I am not a lawyer. Also: possession is nine-tenths of the law, and the AI companies have already trained on the data.
Laws, contracts and licenses are only useful if all parties actually agree to the terms. The written text of the licenses is really only to avoid confusion about the agreement. But the AI companies don't show good faith.
