I think the point is that academic writers use large terms, despite using them wrong, when diminutive ones would suffice.

They use big words for the sake of using big words. Whether they make any sense whatsoever, is entirely beside the point.

The text, as I understand it is essentially saying the same thing, using big words to obfuscate that they're actually saying something rather boring and simple, which also has the point of obfuscating the meaning of the text to anyone who isn't an academic; aka someone who isn't used to such nonsensical word play.

There's a good reason I've avoided any work in academic fields. They incorrectly use terms, which just muddies the water on what the hell they're actually saying. Not only because the terms are big/less known, but because they're often used wrong.

IMO, academics are morons who like to sound smart.

... Do you concur?

I think the meaning of the actual words that he chose is less important than the fact that it sounds absurdly convoluted.

Also I don't think his point is true. If you read academic papers come up most of them are pretty easy to understand.

It's saying that it uses terminology that is well-understood, specific and explicit within the field, but depends on a common understanding of the language used. So people outside the field are unable to understand it, even though they would be able to understand the actual concepts.
