I admire you taking personal responsibility and actively refusing to support systems you see as wrong and harmful. But, echoing what others have said, as a vegan and previously vegetarian of many years, I think there's probably a better way to describe this than "AI Vegetarianism". Both so that people take it more seriously, and to avoid adding even more confusion to the already misunderstood topics of vegetarianism/veganism.

While you're at least trying to use the term in a positive light, it's not hard to imagine people using the same terms "AI vegan" and "AI vegetarian" in a disparaging way. The implication is "vegetarians/vegans are preachy/crazy/annoying/arrogant" and using that to describe someone who's anti-AI. E.g. "Oh don't listen to Bob, he's just an AI vegan" or "These annoying AI vegans keep protesting outside and blocking traffic". Now vegans/vegetarians are dragged into something they have nothing to do with, AND you've given detractors an easy way to mock you.

How does one know if a stranger is vegan?
