There are valid reasons for limiting which topics people can discuss in a space, in my opinion. If I disallow people from discussing politics on my cooking forum that's not censorship. It's keeping the discussion focused on the actual topic. HN seems to take a middle ground position of allowing politics when they are relevant to the topic, but not otherwise. That is also what I promote on all platforms I moderate.
