The concept of "Servant Leadership" is not exactly new [1], Many people are not in the position to argue with their boss when they frame it as an adversarial relationship - That you owe something to the boss for your pay, that it's somehow a privilege they are granting you to work for them. There's no way to prevent those kinds of leaders from having a successful organization except by refusing to work for them and out-competing them, and fundamentally: Crime does pay, sometimes for long enough to starve legitimate competition out.
