Too Much Generalization
The Items listed in the article do describe characteristics that could be interpreted as incompetence. However, one can easily imagine scenarios that make such characteristics understandable or even laudable. For instance, the Deadlines issue. How many of us have worked in environments where the deadlines are set by the sales staff for the IT staff? Only an incompetent manager will comply with those deadlines. Deadlines must be arrived at with a proper amount of analysis and consideration of all factors, including the emotional well being of the development staff. Too many 80 hour weeks and you lose your best people. A competent manager says no to bad deadlines and takes the heat for the employees.
We could build similar scenarios for most of these, if not all.
