Lemmy.ml has fully went communist even their application needs you to copy paste a part from a communits book and that’s ok by me every politkcal group has their own instance and has the right to do as they wish . But they should really change their about from foss and privacy advocated to communist leaning .
ml hosting communities outside of their actual scope is actually detrimental when federated elsewhere. It gives the impression of general interest or even niche communities and users that are available to you, but which are also secretly conditional on you being a tankie.
Lemmy’s design (unwisely) means instances “own” both accounts and communities, and also that an instance that just doesn’t like you could cut you off from swathes of people and content. That is not even necessarily bad if it’s done for honestly stated reasons, it’s fine and necessary for parts of the fediverse to curate themselves and have varying rule sets. It is bad if it’s done under false pretenses. Federation means things show up at an equal footing, and that leaves no room for instances to be dishonest about what they are.
ml, based on its behavior, is a highly niche server and that niche is not primarily foss or privacy.
