People in the instance have more varying viewpoints since its oriented towards a niche/content category (+ same is true for other niche instances). People interacting in the instance can be managed but its difficult for people interacting outside to be moderated to make sure theyre actually following our rules since admins dont get reports of people in their instance being reported, only the instances of where they interact in do.
Politics communities (aka communities that only talk about politics rather than something like a hobby (and lgbtq+ isnt politics)) are now hidden by default on the instance though hence why you probably havent noticed the two are federated still since people dont stumble in and need to explicitly choose to see the content (leading to less people arguing on different politics communities since they just sub to the one they want and then sees that one as normal)
