Because an advice without argument is ignored (in many cases). If it were me I would have rephrased my comment to include a summary. That would be sufficient to understand why you said things and in addition would be perceived less cocky. Now it came over as I'm saying this and you are not worth my time explaining the arguments. Apparently you have knowledge on the subject so a sentence or five would have helped everybody reading this thread. In fact, it is what I would expect from an HN comment. I usually read the comments before the article as on HN there is often more information than the actual article. Most often different sides of the coin are in enlightened in the comments bringing insight in the otherwise one-sided monologue in the article.
