The engineering tyrannical drive for plain English doesn't fit in the web's protocol philosophy. It's a place where all styles and forms belong. "Written communication" is by nature jargon when specializations are interdisciplinary, otherwise monoculture takes root. If you don't understand something, ask or search - this is the web, dude. Nothing ends here.
The critique you're dismissing is from an English professor who teaches argument, not "engineering." So your writing is in fact being criticized by both "CS" and "English" (as you might put it). I'm not implying that taking license with punctuation, vocabulary, or grammar is necessarily bad -- I studied writing under two poet laureates, so I'm no stranger to unusual syntax -- but what are you writing on an Internet forum for if not to be understood? Your arguments against writing more plainly are quite familiar to me; engineers make similar arguments when told they need improve their documentation or user training materials.
