Note that you can't discuss this open letter -- or any issues of that nature -- openly in the official places (NixOS Discourse & Matrix), because there is a risk of getting tarred as "fascist" or "concern-troll" before getting banned. Someone named Ailunarenth respectfully engaged in such a discussion only to get banned:

If you post in Discourse, it is likely to get "unlisted" (meaning censored from Google and other search pages) by the mods. A case in point: you can't reach this post without a direct link (the open letter alludes to Jon Ringer being one of these 'fascists'):

I myself got banned for a picture of a steak and a link on my website, back in November last year:
But none of this is surprising because "ejecting fascists" (where 'fascist' means "someone whose opinion I don't like") has been the theme of these activists since 2021. See the downvotes in this sensible comment: https://github.com/NixOS/rfcs/pull/98#issuecomment-902913333
Yeah, what an annoying person, I wouldn't want to work with him either. At least most people with this world view don't cloak it in a layer of reasonable sounding but devoid of substance discourse that wastes everyone's time.
