My issue is that OP is not providing any solid proof. They are just giving 'wink wink's about some 'popular' instances doing it. When asked whether they have proof, OP says they has proof of some mods doing it. Mods don't handle instances, admins do. They haven't yet provided any concrete proof, yet creating an impression that some instances are banning en masse using LLMs based on "political ideology".
If you're not going to name them, why post here at all? Don't you have other communication channels to "give them a fair chance to reply"? Why post here, letting users form their own assumptions about what those instances are without any solid evidence?
Any other country is just a copy of the usa with a 'slightly worse', or ' slightly better' modifier.
