Hell, your comment is full of jargon. "Yuppie", "buzzword", "suit" (and "empty suit"), ...
[0] though it's usually very contextual when that's the case, which is really frustrating when things are taken out of context and either become completely unintelligible, or easily misinterpreted (and sometimes wilfully misrepresented).
Avoiding business jargon doesn't mean having to stick to the 1000 most used English words.
Which the article points out, though not plainly, should be avoided.
In any case, your language here would certainly run afoul of the "simple English" the OP is espousing, and the OP terms such things "jargon", so contextually, yes, it's jargon.
Although personally I agree, the OP is using a particularly sloppy definition of "jargon", which often has a stronger technical connotation than merely metaphorical or business newspeak language.
It means “young urban professional.”
Sorry to burst your bubble but that’s jargon.
> Yuppie isn't jargon, I was thinking about the movie American Psycho.
It’s also jargon.
> It's just a term to refer to your stereotypical middle managers high on their own farts.
I know what those terms mean.
> business jargon
Oh wow look at those goalposts flying by, amazing.
When I wear a T-shirt from a Hackathon to a developer conference I'm signalling just as hard as the sales rep in the suit.
It doesn't necessarily mean that I'll have to go the other way and adopt the mannerisms of the annoying tech guy.
> and we're back to the 1980 where middle managers in business suits are the cool guys.
Nope, we are at the 20's, when social-only corporate climbers know not to use suits on development-dominated cultures (not software development, but "creating new things from known principles" development). So suits are irrelevant nowadays and lost all signaling meaning.
Those hackers got cool and became the guys in the suits. Dollar Uber Alles
I think it's starting to go the other direction. As a technical-minded person if I have a business meeting and the other person starts throwing those yuppie buzzwords in my face I'll just mentally put them in the "empty suit with an MBA" bin.
It might be my Southern European sensibilities, but I value straightforwardness very highly than time wasting nonsense to signal you're part of the in crowd. Unless the hacker ethos has died, and we're back to the 1980 where middle managers in business suits are the cool guys.
