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.
Because when fans got outraged about how these films disrespect the cannon's of the universes in which they belong, the people on the left call them bigots and sexists. Despite people generally being pretty positive of side cannon projects like Rogue One which were female driven. It's not that people don't want female heroes, it's that they don't want the existed male heroes shoved aside for the sake of some Fan Fiction replacement.
First of all, you're assuming an agenda other than just chasing trends. And a lot of criticism directed at the things you mention were in obvious bad faith.
That's what people on the left were rolling their eyes at.
Chasing trends is something the entertainment industry has been doing since time meant shit, bro. I have no solutions to that because 1) it's not that big a problem and 2) as long as there is a profit motive, trends will be chased.
And look, I'm kind of a film nerd myself. I have subscriptions to multiple streaming services, the Criterion Channel included. I watch a lot of movies, but not many new ones because most of them just don't appeal. It happens. There aren't enough people with my specific tastes to pander to and expect a major box office draw. That's okay, because that's what independent media is for. The idea that trying something different is inherently "disrespectful" is in your head.
To be more accurate, it's not that people don't want female heroes (though let's be real, there are a lot of neckbeards who would prefer women remain objects in media), they just want everything in a franchise to be exactly the same as the first thing they liked about it. They want things to stay the same way forever. To quote Inside Job, "Nostalgia is a disease that causes adults to argue about Ghostbusters while the world burns." Just let creative people make stuff. If it's not for you, then it's not for you. It's not a big deal.
