I think you might have misread OP. The first quote you extracted isn't their description of the author, it's their description of what the author is conveying in TFA, and that's honestly a pretty accurate way to capture the piece. TFA's section giving the reasons why you might consider a microservice architecture basically boils down to "if you already have microservices, if you absolutely must use a different language, or if you're an irresponsible idiot". That's not the attitude of someone who is open to the idea that someone reasonable might make a different choice than they would. What OP actually has to say about the author themselves is that people who write like that "usually have no idea what they are talking about", which is also absolutely true in this case. There are many tells throughout the essay that give away that the author has very little experience operating any type of system, microservices or otherwise.
