Disney doesn’t want to offend their base.
David Ehrenstein ("gay PC terrorist" himself -- his own tagline) wrote a history of the Velvet Underground. He told me online one time that the illustrators at Disney back in the day were all gay (why all gay, unless they formed a little cartel and railroaded the straight guys out of the store?), and the managers realized it and were careful not to offend them. Over time that made Disney a "gay-friendly" shop. Presumably it's a closed shop now.
But that is what is behind all of Disney's gay-catering.
