I think you're confusing biz jargon with marketing. Tech jargon suffers from marketing too; it's just that we're used to so much more "meaningful" jargon that we see that the bullshit ratio is actually pretty low. The same can be said about business jargon, it's just that we don't hear the meaningful jargon a lot. Want to guess how much meaningful tech jargon the average MBA hears? Probably not a lot more than we hear about his world.

Want to come build a distributed social cloud web app with me using node?

The real problem is when the meaning of a word or phrase becomes so broad that it conveys no information, or gets swamped by overuse and becomes a buzzword.

That's because you're not a biz person.

I've had business types say exactly the same to me about tech jargon.

You do not work at a telco do you? There are so many abbreviations floating around that it sometimes is very hard to figure out if it is business bullshit or not.
