I think it stems more from how a lot of companies turn a bit of a blind eye towards fan creations when in reality it’d just be far more damage to their public image going after stuff for close to no actual gain. Though from rumors I’ve heard the Yakuza connected with horse racing were making threats towards people that drew the girls from Uma Musume naked which is kinda funny TBH.
