I think the article was useful and worth keeping up. (However it seems that the author himself unpublished the article from his Substack.)

All of the visceral reactions to the article are... very revealing. It's an opinion piece, and you don't have to agree with it. If you felt angered / hurt / offended by the author's words, I would challenge you to do some introspection – and explore the reasons why it generated such a strong reaction for you. You may find the process to be quite beneficial!
