ESCHEW OBFUSCATION.

That's a polite way of saying "enough with the garbage language."

What makes it "garbage" is that [what I call business bafflegab] fail to communicate anything that couldn’t be said in plainer English. Their function is often to obscure meaning, not illuminate it. But that doesn't mean “garbage language” is used for the same reasons by everyone who uses it.

It's common enough in higher education as well as in those endless presentations in the conference room, and it's fake. "The problem is that using the language is easy. Doing the work is hard. And constantly using the language can seduce even the most conscientious of us into believing we've done the work when we haven't."  Or, as the essay suggests, to signal one's erudition and proper moral stance.
