I think someone used ai to mean attribution/alike, international. Which are part of the full name (Attribution-NonCommercial-ShareAlike 4.0 International) but still make little sense as an acronym next to CC BY-NC-SA 4.0 being the official acronym.
There's no point looking for logic. These people truly believe granting a licence restricts the rights of people who don't agree to the licence, which is the exact opposite of what licenses do. It's blatant misinformation but if you call them out on it (even by quoting their own link) they literally think you're an astroturfer for AI, because that makes more sense to them than the fact they're obviously wrong.
The only thing worse than the tech-bro's worshiping AI like it's the next messiah and we all must pave way for this revolutionary technology that will only seem to benefit white Americans with disposable income, are the people on the opposite end of the spectrum who are have a hysterical hatred for LLM's because their favorite Youtube streamers are getting clicks by ranting about how bad AI is. They are not being personally impacted by AI at all but are delusional enough to think that there will be laws and regulations and that AI will be "banned" if we all "raise awareness" and it's about as useful as the Bud Lite protests but not even remotely as entertaining.

This person may be confused, but still your tagline is a waste of mods’ time. And just speaking as a user I find it to be annoying visual pollution, especially since I think it’s ineffectual, unless your only goal is to “raise awareness.” Beyond that I think any effectiveness is about as plausible as that of sovereign citizenship.
