I think one reason is also the style? Like you can not like the LLM style and that's a perfectly valid to reason to not like it.

Attacking the use of LLMs might just be shorthand for the style or the long-winded vacuousness that people don't like.

I agree that if someone used an LLM and the result is _good_, I'm not sure I would care. But that generally doesn't happen yet, so one is a proxy for the other.
