Those are all characters from Disney movies though. Albeit older ones, but still part of the studio's body of work.
I don't mean to nitpick. I only bring it up becuase there are large swaths of the guests who visit in recent years because they like the classics, but couldn't care less about the newer stuff. They want to share with their kids the stuff they came up on. They'll go on Guardians or Ratatouille, but they want to share the classics they enjoyed as kids.
The company's strategy involves that notion, as well as using the parks as an advertising vehicle for the latest and greatest the studio has to offer. For example, slapping Asha from Wish in EPCOT before the movie even came out.
