I dunno. My comment complained about the parent comment not adding positively to the discussion. And gave at least a bit of support for that complaint.
Would you have preferred I emulate your style, and complain while providing no support for my complaint?
Being positive is not a requirement of commenting on HN, but you should comment with something that is substantive, so yes I do think you shouldn't have commented at all. Tone policing is cringe.
I don't like tone-policing in general. But when I opened this post the negative comment we're talking about was the top comment. That's makes me much more sympathetic to someone calling out the cynicism.
