Which off-topic rule? Non-technological topics are more than welcome, here.
" What to Submit On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic"
Unless I am to read this fragment to mean "gratifying one's superficial fetish for frivolous novelty", why wouldn't this article satisfy this criterion in a general sense? Feser offers an analysis of what he takes to be the moral hazards of the material prosperity, etc of capitalism. If that can't be said to be a topic of interest, then I'm sorry, but IMO, that's an indictment of the accuser, not the article.
I read articles on HN every day that are far less substantive or original than this blog post. Plenty of posts are off-topic if we go by the description above. And articles on the subject of capitalism have been featured on the front page just these last two days which is why I thought this article's publication was especially opportune.
I don't wish to make accusations, but it's difficult not to suspect prejudice.
