Blog posts are aimed at an audience, HN is an audience, and in both cases the audience in question is a technical one with an above-average number of well-paid professionals. The whole framing that the blog post "reeks of privilege" to "most people" is a bit strange. If I were to read a Yachting Monthly article about The Five Most Attention-Grabbing Mega Yachts For The Conspicuous Consumer Billionaire it would probably reek of privilege to me, too, but that's an entirely self inflicted problem: nobody is making me read a specific article from a yacht magazine.
