The license still allows AI training theft. What is needed is an OSS EULA that forbids IP theft, since the governments are corrupt and still allow it.
The EULA needs a clause that 10% of the market cap of a company will be paid to the IP holder upon violating it.
That is a lost cause, because the AI companies are above the law now. Copyright doesn't apply to them, felonies committed by them (via their agents) are not prosecuted, and if the AI bubble were to burst, they would be bailed out because by now, all American pensions and the ETFs of the rest of the world depend on them staying fantastical capital black holes.
But what we still can do is stop programming for free for Big Tech, and this license at least gets us closer toward that goal.
The current argument AI owners use is that it falls under fair use as "transformative use", so the licence is entirely irrelevant. If that wasn't the case anything trained on GPL code would have to be released under the GPL.
I'm now sure what if any argument they are using in Europe. Most countries here have a "fair dealing" exemption which is similar to USA "fair use", but it doesn't include "transformative use". The closest would be "pastiche", but that wouldn't really cover it.
