I don't think people are being too harsh. He put his opinions out there in a very proscriptive way. He didn't invite discussion, he merely dictated his opinions. And he is quite wrong. Additionally, his blog is called ProgFu. That gives the impression that he is highly skilled and experienced; an authority to be heeded, like the sensei of a dojo. But if you look at his writings in total you can see that he's pretty green. His factual pieces are really useful, the opinion pieces less so. While I'm thinking about it: I'm dismayed by this trend of bloggers dispensing programming advice like they are Miyamoto Musashi himself (although he would never display such hubris). Exchange of information is what's important. If you have a personal experience, share it, and perhaps discuss the lessons you've learned. But, please, don't write articles merely stating your opinions without backing them up with some evidence or experience.
