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.
