The only portions of the work that can be copyrighted are the actual creative work the person has put into the work.
Ok, but it's not like everyone is documenting exactly which parts are generated, curated, or human written.
Maintainers cannot prevent the LLM code from being incorporated into closed source projects without reciprocity
Say someone incorporates GPL code without attribution, and gets sued for doing so. They try to make the argument in court that the source material they used is not copyrighted, because of AI. Won't they have to prove that the parts they used were actually AI output for this defense to work? It isn't like people are going around ignoring the copyright on things in general if they look like they were probably generated with AI, that isn't enough to be safe from prosecution, because you usually can't know the exact breakdown. It seems like preventing this loophole from being used would be as simple as keeping it ambiguous and not allowing submissions that positively affirm being entirely AI generated.
