First, there is a complete lack of empathy for the person being labelled. What are the motivations and constraints that led to this person acting this way? A key question and the foundation for building healthy productive relationships.
Second, the 'solutions' are horrible. "Go around the person" is terrible advice for anyone on a team. If you follow the advice from this website you will end up being the problem.
I would argue that this website is almost sociopathic-- completely ignoring the perspectives of anyone but the reader and suggesting damaging solutions and labels.
