What was incorrect (to use your word) in your posts in this thread was your misalignment with the intended spirit of the site. You responded with generic/shallow objections to someone's creative work. That's one of the failure modes of internet discussion, which is why both the HN guidelines (https://news.ycombinator.com/newsguidelines.html) and the Show HN guidelines (https://news.ycombinator.com/showhn.html) ask commenters not to do this.

It's true that the repliers crossed into the red as well, but fundamentally that's a healthy immune response going a little too far.
