I fully agree that the majority of Lemmy users (and probably Mastodon, though I haven’t checked) appear to be authoritarian Marxists, but both my local syndicates and the international workers confederation ICL-CIT have active Mastodon presences, so there’s definitely an effort by anarchists to move away from corporate-owned communications platforms. Could do without the marxist-leninists though, who sadly seem to make up 100% of the Lemmy dev team.
It already runs a lot better on Steam Deck than what it used to around launch. The series S port really helps with that, probably.
