The article addresses a real problem. Haskell is presented by its neophytes as some uber-arcane thing that cannot be understood by a mere average programmer, you have to learn algebra first!, and read all Martin-Lof, and whatever else. And it hampers adoption of the language by many other people who might be offended by such superiority attitudes.
However, it is much healthier to present Haskell as simply a tool for writing better and safer code, which is frequently easier to reason about than your conventional for-loops all the way down. So everyone should try it, and say for themselves.
I may be wrong and over-generalizing here, but Haskell is a very convenient vehicle for showing off and belittling others. And honestly, who does not want to stick Haskell somewhere in their CV just to look better nowdays? Being fancy has a cost for the language. This is not an intrinsic fault of Haskell. People just need such a thing. If there were no Haskell, we would have APL, Lisp, Erlang, C++, or something like this.
