There are plenty of such repetitive/indignant symptoms and one of our jobs is to dampen them so they don't crowd out the things that actually are interesting to read. If we didn't do this, HN would consist of almost nothing but sensationalism, indignation, and the few hottest topics of the moment (ChatGPT these days). It's our job not to let that happen.
Having a separate comment section for this kind of thing would be a moderation nightmare and I don't think it would add to the quality of the site—quite the opposite. I once had a conversation with a founder of a (much) larger forum than HN, who told me that creating such a section (or something recognizably like it) was the biggest mistake they ever made.
I hear you about the frustration though. It's true that HN lacks a lot of features. There are many different ways to structure an internet forum/community—many more than have ever been tried, and I feel sure that there's still plenty of room for new ones to flourish. People feel understandably frustrated when this forum doesn't match the one that they imagine and believe (perhaps correctly!) would be much more satisfying.
