On the subject of technobabble, it's a blessing that Star Trek(the original series)did not overuse such scientific accuracy and realism.
Unfortunately, TNG, DS9, Voyager, and Enterprise did. And most of that technobabble did not make any sense, or help the episodes of the aforementioned useless spin-offs under Rick Berman's reign. If anything, all it did was just hinder the episode and made the story boring as hell.
While it is great to use realism in a story, especially science fiction, overusing it(i.e. the technobabble)can just run the story into the ground. That was one of the other reasons why Star Trek entered that period of franchise fatigue after the ratings and box office failures of both DS9, Voyager, Enterprise, and Star Trek:Nemesis.
Rick Berman, and to some extent Ronald Moore, obviously did not take their artistic cues from the old school of cinema and television arts. Something that the late Steve McQueen and Paul Newman often used in the perfection of their respective crafts.
That something being 'less is more'.
Neither DS9 or Voyager were the ratings failures you suggest. If they were, they certainly wouldn't have lasted 7 years each. Furthermore, DS9 wasn't a major offender on the technobabble stakes, thought it certainly had its moments. Nor was Enterprise for that matter.
Moore's no fan of technobabble, and if you actually watched his work rather than declaring it worthless based on a narrow cross-section, you'd know that.
