Disney twitter is especially bad because a large portion of the influencers are both financially and personally vested in the topic. People who have moved to be close to Disney, people who have worked for Disney, people who now make their living being Disney parasites, people aspiring to make their life be supported by online Disney content, etc.
So many are in so deep it drives extremes. And add in the lifestyle angle? It's a bubble of insanity.
Contrast that with say, most Car fanatics or Sports Teams fanatics... most don't dream or change their life to be closer to the team/company
