As pointed out (arguably a bit harshly) in comments under the original article, this is really a strawman argument. That's because that ol' classical GoF book on design patterns - which the author admits has not even read - addresses this concern already. It's still a valid argument, but not exactly a fresh one. And speaking on the subject without even bothering to read the piece widely considered as canonical is a bit arrogant.
