Here are the demands from the WGA:

Their proposals were:
>Regulate use of artificial intelligence on MBA-covered projects: AI can’t write or rewrite literary material; can’t be used as source material; and MBA-covered material can’t be used to train AI
I agree some aspects are about writers protecting themselves from being replaced by AI, but the outright ban on use of them (ie. "can’t write or rewrite literary material") and prohibiting them from being trained seems consistent with the parent's claim of "There is a large group of people who don’t willingly uses new tools when those tools enable all comers to make better, “competing” work product"
