Me. Because I used to love reviewing conference papers and AI has utterly ruined it.

If the end result was reliably good people wouldn't be hating on it, but the vast majority of people are using AI not to elevate their output quality, but to churn out slop quantity, because that's where the incentives push them.

Anyone who actually engages with the output can tell that the speedups you get on producing good prose, maintainable codebases or high quality abstractions are much much less because you can't let the LLM go brrr, so AI output tends to be drivel, and banning it is a good way to prefilter.

It'd the same reason journals and conferences desk reject you if you don't follow their formating rules or don't use their template - it's a price of admission that ensures some consistent quality level, and if you couldn't be bothered to learn how to follow the rules, why should we trust you that the content is worth out time?
