I don't know what Dang's side of these accusations are, but it certainly sounds bad. In the mean time the title of the link doesn't match the content served.
I am not sure what to make of the accusation that Hacker News is more and more a haven for alt-right. I certainly saw a shift to the (MAGA) right along the general maga-isation of the US right and I occasionally see unhinged comments of the type you probably can find on truth.social (why do I feel they should have called it TRUTH full caps, that'd be more like them ) but I feel like the moderation of the website works reasonably well at weeding out the unhinged and providing people with somewhat reasonable conversations (the ones with real bits of argumentation inside). They keep repeating the accusation but they don't provide any actionable demands to make things better. Even then not sure what the "administrators" could do about it. Saying that targeting individuals for how they want to live their lives is bad in the guidelines ? Would that make much of a difference ?
EDIT: I just check and of course they use full caps in their logo, I should have guessed
I can't really make sense of the more general accusation but the "countermeasures" accusation was hacker news removing some http field/attribute (?) telling their servers the request originated from a link clicked on HN so they could not block traffic originated from here (which they were doing)
I fail to see how this was such a big issue to them. The admin probably felt like it was not cool to discriminate against traffic from the site and bypassed their block.
When they complained about it meaning it wasn't just a stunt but quite important to them, it was removed. Much ado about nothing imho.
