I'm not sure that kind of middlebrow rebutal makes sense here. I took issue with the content of your critiscism, you with the fact that they were critical at all.

And, it's feedback turtles all the way down.

You might want to avoid reusing reddit phrases like "let them have their fun". That was probably the bigger source of agitation that anything you actually meant to say.

HN wants to hear you elaborate your own take rather than just blindly defend things on moral or ethical grounds. The comments are the lifeblood of this site and a lack of nuance ruins discussion. All anyone can do is either agree or disagree with you at this point, and that's no fun for anyone except bots and people who have no life.
