I think the problem goes a bit deeper than that. From an IP perspective, I think it's reasonable to consider that training an AI on some form of work is using said work to build a new one, just like it would be if it was manually copied in or reproduced. The problem is that, iirc, GPL didn't consider this at all and still uses language focused on copying code, so something like copilot might slip through the cracks of those definitions. Then again, the license uses this language when it allows usage of the code in the first place, so one could say that either a) this usage is covered by the license, in which case all conditions apply, or b) it is not covered by the license, in which case... github wouldn't be allowed to use the code at all. To give an analogy: I think feeding code into an AI is essentially analogous to compiling the code. A machine turns it into something more usable and the original human-written content isn't part of the result anymore, but the intellectual property gets dragged through the process nonetheless. Why would it be any different just because the mechanism of transforming the code into executable software gets a bit more complicated through the usage of AI?
