You seem to be ignoring the importance of centuries of concern and acquired wisdom on how important good communication is, by emperors, CEOs, managers, ... etc., for maximizing the value of any relationship.
People are not interchangeable, with regard to any skill. This is even more so for communication which is a meta-skill over many skills.
The upside to greater communication effectiveness is higher performance with regard to skills downstream from communication (almost all of them, almost all the time).
Dismissing the job of adapting communication styles or substance to one side of any relationship just leaves upside potential on the table, or locks in unnecessary downside. This seems antithetical to what management is about - maximizing the value returned by those being managed.
