A lot of academics and "journalists" do this for various reasons. Zero Books is really bad about this and I think it's almost necessary with how unpalatable leftist views are to "the proletariat". They use complicated words and sentence structure, colorful graphics, simplistic good v bad binary, and simple terms in propaganda videos, depending on the format and target. Doctoral theses, pseudo intellectual "educational" channels(PhilosophyTube, Knowing Better), animated breadtube videos(Extra Credits and the "I Hate Mondays" video creator), and PragerU ripoffs(Gravel Institute) implement these(loosely in that order).
One Zero Books video comes to mind where the narrator describes a Halloween world where starburst is used as currency and trick or treating is every day. Almost the entire video is description with a statement at the end that people may not like starburst or become sick of them. At no point does he explain the message he was conveying which may have been about how currency is bad. The viewer could also interpret the video as a fictional example of the failure of the barter system.
Theses in marxistic studies seem to use "word salad" as a method to signal intelligence and membership of academia, at least in my experience with them.
