I know plenty of vegans that will not eat anything "contaminated" with animal products, no matter how those were sources. I also know people who simply avoid animal products. There's a big difference. Simply limiting consumption of animal products as much possible is normal thing people do out of ethical and environmental concerts. Refusing to eat already prepared dish because it has some animal based ingredient is simply wasteful. Same with LLMs. There's a difference between AI slop and LLM assisted coding. People who refuse to see the difference are as annoying as overzealous vegans.
