I guess it depends on how you read it. I read that statement in a humorous tone as-if the author was amused by it. It didn't sound angry to me. I do appreciate the ability of an author to simultaneously inform and amuse. Many people (I'd put myself in that category) are looking for interesting news articles, that are not just a boring list of facts. I'm not a follower of the authors work, but as far as I can tell there isn't anything important thats factually incorrect in the article.
