after 33 years online I can confidently say that "censorship resistance" is overwhelmingly a right-wing shibboleth

The "censorship resistance" being criticised here is in support of free speech absolutism: posting propaganda, misinformation and brigading and trolling people with no recourse. This is bad and has real and meaningful consequences for people like Jason Arday who was recently driven-to-suicide for being black and successful amid false plagiarism allegations and a media witch hunt.

I agree that left leaning causes also need resilient comms infra to allow for organisation. Unfortunately these issues are two sides of the same coin. I think it is completely fair to criticise people like Dorsey who left bluesky in 2024 because of their moderation approach which is hardly heavy handed - especially if you are a far right hater of trans people . We can condemn this behaviour and also hold the belief that we need resilient infra that the government can't easily seize.
