You broke the HN guidelines badly with this, first because of the name-calling and personal attack, and second because it is a shallow dismissal in exactly the sense we ask people not to post here:

"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something." - https://news.ycombinator.com/newsguidelines.html

On the plus side, your comment does contain some specific observations which could have made for a good comment—one that communicates interesting information respectfully. If you'd please post that way in the future, we'd appreciate it.
