To some extend that's true, but it was always in service of the story. What's happening at Disney is just the opposite - they're randomly inserting ideological stuff which has no relation to the story or they're contorting stories in support of an ideological narrative.
And I don't care what your politics are, but when you insert politics into a story, your gonna alienate a major part of your audience OR you're going to the ruin the product experience of consuming TV. When people sit down to watch TV, they just want to relax and escape. Inserting politics, pulls people out of that and gets their blood pressure up. Who needs that?
We don't need a "very special episode of.." every week.
Yes. In many cases, it is the ideology that forces the bad story.
In the last two movies, all the men had to fail, the ideological bent to the story required it. That's why we got Luke as a failure, Han Solo as a failure (he couldn't redeem his son, only Rey could through the power of ambiguity), and Finn as a failure.
Imagine if Finn had succeeded in his sacrifice. How powerful would that moment have been?
Instead the story we get is one where morality is an old fashioned idea. Hard work and merit (Jedi training) are "the old rules that are holding you back." We get the whole "there's no good and evil, there's just power." All of which fly in the face of the original world of Star Wars. Patience, self-control, and practice were virtues. Anger, impulsiveness, and fear led to hatred, evil, and suffering -- the Dark Side.
Rey can't be trained, because it would mean a man was training her. Leia can just develop Force powers on her own, because otherwise, she would have had to learn them from a man. Poe Dameron can't have a proper perspective on the battle or be trusted with any plans because the point of his character must be "toxic masculinity."
It made the stories of these movies suck. Contrast that with how Andor and The Mandalorian deliver female characters that are amazing. Leia is a true badass... as she was in the original movies, without the Force. Bo Katan's character goes through a deep understanding of what it really means to lead her people, and earns it. Strong women, that don't require a man to fail, in order to be strong on their own.
In "Falcon and the Winter Soldier" there is a random scene where the police hassle Falcon. (this was shortly after tragic George Floyd incident). It wasn't part of the story, had nothing to do with the plot. Why was that there? The first thing they teach you in dramatic writing is cut fluff. That was fluff that just got people worked up.
"She Hulk" also was filled with political narratives.
And again, I'm not taking a political stand here. I'm just saying when I sit down to watch a Marvel show, I want to escape and have fun. I don't want to be reminded of controversial political issues - unless it's essential to the plot. Otherwise, if I wanted to watch a show about politics, I'd just turn on the news for free instead of paying for Disney+.
Side note: I heard second hand from someone who works at Disney that Tune out Times (ToTs)- when a user stops watching a show, spike at these things. The data is telling them they're aggravating their audience, but they just keep on trucking... God knows why. They're a business, not a political activist group.
There is a difference between the progressive ideals of the previous generation and the current generation, if anything the current generation of progress ideology is more regressive than anything else.
