I really enjoyed reading your article and the previous one. Indeed, it is important to clear up our vocabulary, but in my mind, in any case, words are just placeholders for an emotional subtext which is what humans truly react to beyond the words. Take two people, make them read the exact same text, for instance Greta thunberg and Donald Trump, and I assure you that people will react completely differently to it. The choice of words our actually a very important piece of unconscious information for both speaker and listener. For instance, as you rightfully point out, in many cases when using the word "quantum", people try to appear more scientific. It's a very important unconscious message to the listener as he/she can detect an attempt to impose one's point of view using scientific terms, or an attempt at disguising one's lack of confidence in what they say by hiding behind technical terms. Perhaps poor use of language contains a hidden form of communication. What you have done is explicitly laid out what some of those hidden messages may be. The question remains whether we should get rid of them or rather, whether we should simply become conscious of these hidden messages. Cheers! ;-)
