I don't really know what to say. So let's make something up.
How would you solve the problem of these companies taking existing properties and ruining their established storylines to insert their own agendas? For example the new Star Wars Trilogy, or Terminator Dark Fate, or Ghostbusters 2016.
What agendas?!
No, seriously, what agendas? I...okay, fine, let's go through this IP by IP.
First, Star Wars. Yes, you can make a reasonable case that the sequel trilogy ruined the old EU. That's valid, I sympathize with it. However, the 'agenda' you're talking about is Disney wanting to make money. That's...not exactly an agenda, that's a mission statement. If Disney bought the Star Wars IP, and wanted to make movies from that IP, then I can understand why they'd want a clean slate, because spoilers, far more people watch the Star Wars films than read the books and whatnot. And if you want to complain about elements of the sequel trilogy ruining Star Wars, such as Palpy's return, or how it's largely a retread of the OT, or any number of writing decisions, sure. But that's not an agenda, that's just poor writing.
Second, Terminator. I don't know how you can claim Dark Fate "ruined the established storyline" when stuff like T3 had already done it long ago. Was T3 following an "agenda?" Chances are, if T3 was released today, people could claim that, given how powerful the T-X is. Or what about Genisys? This isn't me speaking my own mind (I genuinely like every Terminator film bar T3), but to claim that Dark Fate "ruined" the storyline is to ignore everything that occurred after T2, film or otherwise. And even in a hypothetical scenario where Dark Fate existed and nothing else, what "agenda" did it have?
Finally, Ghostbusters 2016. How did it ruin what came before when it's in its own continuity? It's not as if Ghostbusters hasn't had alternate continuities before - the Ghostbusters cartoon (followed by Extreme Ghostbusters) went in one direction, Ghostbusters 2 in another. Did Ghostbusters 2 "ruin' the storyline of the cartoons, because they're mutually exclusive canons? Because that's the argument being made.
Of course, I know the real reason, namely "da womenz," but surely you can see how absurd your claims are.
Despite people generally being pretty positive of side cannon projects like Rogue One which were female driven.
Rogue One has one...ONE...female character. Two if you include Mon Mothma, and she barely features. Using Rogue One as a "I can't be sexist, I like Jyn Erso" isn't much of an excuse.
Now to be clear, I don't think disliking characters like Rey or Holdo, or dislking the sequel trilogy makes anyone sexist ipso facto, but Rogue One isn't really the bastion of 'good feminism' that you think it is.
