Star Wars is an awkward example because it’s already pretty well tainted itself with mediocre films.
But yes, unironically I would actively stop looking for the shreds of good among the carnage that is the once-beloved franchise if I knew its creator, whose name is still tied to it and who financially benefits at least from the propagation of successful entries under that IP, would be just a little bit more able to get their awful views out there thanks to that success.
Your example is unambiguously plural. It’s not a good illustration of “they” creating confusion.
It’s truly not a problem. I could contrive a reason to talk about a couple (they plural) and a nonbinary person (they singular) and end up with sentences where you don’t know which I’m referring to, but the exact same issue happens if I’m telling a story about two “he” or “she” subjects. And it’s solved in the same way.
