I am often torn a bit on this one, depending on the cases.
Don't get me wrong, management lingo is undeniably bullshit, trying to hide how simple what you're saying actually is, and giving yourself stature and legitimacy.
But I would argue that there are fields were the emergence of complex concepts (and lingo, and notations to define them) is a necessary evil. For sure even there, there are people who abuse it to big themselves up, but I also think a lot of the time, either the thing you're speaking of is genuinely complicated, or it's just not well understood enough. Sometimes I really wish I could say things in a simpler way, both in concepts and expression, but I can't find a way to make it so. Not by malice, not to appear to know more, but genuinely because I don't understand it enough yet either and that's the best I've got.
Having experienced it first-hand, I am more forgiving to this (depending on the attitude of the person spouting the jargon) and don't automatically assume all technical-sounding terms are automatically bullshit. They often are, but not always.
But management lingo is. 100%.
