The Fediverse is home to a lot of young, tech-minded people distrustful of major corporations. The younger generations are more likely to come out as transgender due to greater awareness and acceptance of gender identity and dysphoria, and a decentralised, open platform is naturally going to appeal to communists, syndicalists and other left-wingers who don't want some billionaire buying the next website they get comfortable on. And funnily enough, there are a surprising number of trans people in the tech sector, to the point where trans-flag socks have become a meme among programmers.
