Whenever I come across teams with situations outlined as in this article and I talk to the people involved, it becomes apparent that Scrum was implemented for the sake of implementing Scrum without understanding. The values and the concept of empiricism are important to grasp in order to effectively leverage Scrum - that is why you have a Scrum Master, not as a manager of any kind, but as a coach and facilitator.
The main challenge I see people having is that Scrum was designed in a way that it screams in your face when you screw up and many organizations fight that instead of inspecting and adapting their way of working.
