I think there is more to it then that. All my managers have been shit umbrellas, but still some of them were not worth the investment of my time. Once my management was split over several people and that was an issue as well as one could set incentives and then the other would obstruct because they didn't share the incentives and didn't care about the outcome. Not having shared incentives and outcomes has been the most common problem across my entire career. Managers can set up goals and incentives and then change them at the last minute without telling you and claim you failed. Not maliciously in my case, but the effect is the same. I'm sure the ways in which a manager can be bad is quite diverse.
