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.
We don't let our kid watch TV at home, barely watching it ourselves, and have no streaming subscriptions. My American niece, on the other hand, a mere two years my son's senior, has had a TV in her room since at least age 5 with access to Disney+, and my brother and sister-in-law let her fall asleep to it. She was a good little hostess, putting on something she thought her younger cousin would like, and she was, sadly, correct. However, while she had spent her life with constant AV stimulation, my kid couldn't sleep.
I eventually had to tell her that if she wanted her cousin to sleep in her room, she had to turn off the TV at bedtime. This was very, very hard for her, and she couldn't understand why he couldn't sleep.
