That's not a moderation issue. You can post that opinion, and people will disagree with it, post responses to it, and downvote it. It will not be flagged out of existence, unless it's also violating site policy in other ways.
A polite well worded post that disagrees with the mainstream will indeed still exist, but it will be moderated to unreadably transparent and hidden by default. It’s not a great experience.
Meanwhile personal attacks and hyperbole regarding Elon Musk and Trump have become very common on HN.
As someone who actively believes Manifest V3 is good for users, I second this: my opinion is not suppressed by this forum. It's simply unpopular among nerds, the population to whom this forum is aimed.
