LLM outputs cannot be copyrighted.
That alone starts to invalidate the GPL and other FLOSS licenses. It overall weakens the project the more you accept. And companies (MS, Amazon, etm) will gleefully loot anything marked with "LLM" as a free-for-all.
Until the whole copyright situation can be finalized, I'd understand for any FLOSS org to refuse all LLM code.
(Its also the same reason why Oracle also forbids all LLM code in Java and their DB. Same reason.)
