This article would have been a lot better with examples of where that complexity is (particular functions, where the complexity score comes from, etc), and what suggested refactorings help to reduce that complexity. That would make it possible to judge if this is a reasonable metric, or if this is just some overly-strict tool that dings perfectly reasonable code, which some frameworks happen to trigger more than others.
