"Please expand on what you find disagreeable here, else the post is just white noise and not really appropriate for HN." That comment piqued my curiosity enough for me to read the article, something which probably isn't true for over 99% of the comments I read on HN. So I strongly disagree with you that it isn't appropriate for HN. There is nothing defamatory in what he says, and whether or not it is substantive can be decided with votes like all other comments.
