I agree that bluntness is often mishandled, but the sort of language in this article just reads as wildly disingenuous. Obfuscating your actual point (and visceral, human feelings/opinions/experience!) to hopefully confuse your subject into compliance.
Makes me think of that brain-dead article a few years back about how you should dodge offering support in close personal relationships. “I don’t have capacity,” “I’m not paid to perform emotional labour” etc. Sad! Promote humanity!
