It's less the strength of the complaint as much as it is the context. If I'm reading an article about the strengths and weaknesses about functional programming vs OOP, it's fine to include such things. However, I think in this post it detracts from the author's main point. By the end of the first few paragraphs, I was focused more on thinking "Oh, this is another of those rants against OOP" than I was on the actual content.
