Nobody complaints when you invent words or phrases to add clarity, but most academic papers are NOT doing this. It's an academic circle-j** where all the authors play the same game to try to fit in with each other.
And in this respect, you're 100% right. Professionals who make a living doing work, even the ones who know more about the topic than the researchers, are not the target audience. The target audience is the others participating in the circle-j** who determine if the paper should be published.
And no, I'm not saying that researchers are worthless and don't know anything. Merely that they have different purposes and standards for their work. And it has always been this way, in every field.
