There has been a very noticeable increase in this trope in the past few years though. Star Trek, I feel, is a good example. Discovery vs. everything that came before. Call it bad writing or call it execs scared that anything outside the core universe would be too complicated for audiences, in any case I'm glad that's not the route G1 took. Somewhat off-topic, but another trope that we see far too often these days is the "good guys must be the underdog/rebels/freedom fighters" trope. See Star Wars 7/8/9. I always got the feeling that the Decepticons were, at least in the beginning, the underdog. They were the smaller faction, the revolutionaries, the ones who wanted change. I think Animated had a good twist on this with the Autobots being the main ruling faction and the Decepticons being some old war legend. In that sense I find Transformers very refreshing.
