The information in the second and third paragraphs is great, but it's being downvoted because the first sentence is unnecessarily antagonistic. HN has succeeded as a place for productive discussion for as long as it has because it still has an ethos of a joining together in a search for the truth. Prefacing a good comment with an insult (even one that might be true) damages the fragile ecosystem of cooperation. It's not that this particular insult is so bad on its own, but its presence encourages others to reply with escalated levels of confrontation. Downvotes help prevent the incivility from spiraling out of control.
