> The HN moderation team makes a lot of editorial choices, which is what gives HN its specific character. For example, highly politically charged posts are manually moderated and kept off the main page regardless of votes, with limited exceptions entirely up to the judgement of the editors. For example, content about the wars in Ukraine and Israel is not allowed on the mainpage except on rare occasions. dang has talked a lot about the reasoning behind this.

This is meaningfully different in kind from only excluding posts that reflect certain perspectives on such a conflict. Maintaining topicality is not imposing a bias.
