I don't think this article was meant to be widely shared, especially not in a public space like Hacker News. Alexander has a number of articles about depression grounded in actual established psychiatry and is, unsurprisingly, a big proponent of treating it - I'm not sure how you're getting "doesn't advocate for his patients" from this article. Also, it literally starts with the words "total wild speculation". It certainly looks like it's supposed to start a discussion rather than be informative.
