I think decorum works in an environment where decorum is the norm, but we have entered a political moment where that is no longer the case. And I think that this kind of thing bleeds so heavily into culture that they no longer give a shit about having their characters next to it.
They have enough plausible deniability; they did not create the content. I think that's enough for them, in this moment.
And to say nothing of the shoddy quality of their TV shows. Mickey Mouse Clubhouse's lazy CG animation and unimaginative storytelling is shocking given Mickey is supposed to be their signature character. They just don't care. And I think it does have an impact: my kids tired of Clubhouse very quickly and have little connection to Mickey and friends. Compare that to say, Dreamworks’ Gabby’s Dollhouse which they loved.
Disney is propped up by its tentpole features but their bench is incredibly weak. There are only so many Blueys you can buy to make up the difference.
But this past 5-10 years has indeed been quite the drastic dip. You'll have little bits of nuggets here and there because they still have some amazing artists (the '20's mickey mouse shorts are amazing). But you know we're in for a vast decline when they are starting to make even their premier content take shortcuts, play safe, and stifle creativity.
