I think you’re having a pretty narrow understanding of the word “manager”. All your argument ms boils down to an inability to perceive that I’m using the word manager in a general sense, as someone who manages technical developments. I’m not referring to a political manager.

Indeed if the only value added by a manger is to play politics, then I’m not sure whether the word manager should even apply to such a person.

How a good day, and best wishes with your “management” style.
