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.
≤4-year-olds do not care: there's bright colours and motion, and some semblance of story. The point is not to give some kind of lesson, but to distract/entertain (and probably release dopamine). See also Paw Patrol, Spidey Amazing Friends, PJ Masks, etc. None of these seem to have made any attempt at having a 'layer' that appeals to adults.
In some ways I equate this animation style with the algorithmic social media system: meant for 'quick hits'.
Contrast with (e.g.) Bluey.
These shows are honestly fine. They all depict kids working together as a team, solving problems, and navigating socializing with each other. (And in the case of Paw Patrol, some environmentalism. And a few terrible puns.)
It's not like the Smurfs, Rocket Robin Hood, The Mighty Hercules, He-Man, Care Bears, etc. that I watched growing up were that much better.
Meanwhile Prime Video has shows that are basically cartoon cars going through a carwash for an hour. And YouTube has much, much worse junk like rapid-fire 60 second unboxing videos, and morons fake-reacting to various colours of slime.
