It's more of a political stance.

For a good example check out Asahi Linux: https://asahilinux.org/docs/project/policies/slop/

It is the opinion of the Board that Large Language Models (LLMs), herein referred to as Slop Generators, are unsuitable for use as software engineering tools, particularly in the Free and Open Source Software movement.

The use of Slop Generators in any contribution to the Asahi Linux project is expressly forbidden. Their use in any material capacity where code, documentation, engineering decisions, etc. are largely created with the "help" of a Slop Generators will be met with a single warning. Subsequent disregard for this policy will be met with an immediate and permanent ban from the Asahi Linux project and all associated spaces.
