In my admittedly not-vast experience, a pattern going bad because the implementer doesn't understand it is actually only the implementer's fault a minority of the time, and is the fault of the pattern the majority of the time. This is because a pattern making sense to an implementer requires work from both sides, and which side is slacking can vary. Sometimes the people who get it and like it tend to purposefully overlook this pragmatic issue because "you're doing it wrong" seems like a golden bullet to critiques.
