I will not name specific mods or authors as to not cause any flame wars, but I have personally experienced performance degradation & vastly increased bugs with mods that use any form of AI. Not just the ones with AI code - if someone is willing to use a theft machine to create a thumbnail instead of doing the bare minimum of an ingame screenshot + text, or hiring an actual artist (or just politely asking one!), I doubt their ability to be thorough with testing their code.
I'm very disappointed that this is even much of a discussion. GenAI is harmful for a frankly comedic amount of reasons and giving it an inch means giving it a mile. Bare minimum, all AI-involved content should be tagged as such.
