I think the author and submitter got exactly what they asked for by posting something to HN that is by their own admission low-effort as it took only 30 minutes to knock it out. Many of the commenters call this out, since in their opinion the content does not hold up to what the headline promises.
Also, one aspect of professionalism is also to be thankful for the feedback rather than trying to interpret it as attacks.

Is an attack on me personally, nothing about the article. The article also took much longer than 30 minutes to 'knock out' - more like 3 hours all in all
