Another trick, which no major studio would ever invest in, is to defang them by mocking them. There is literally no weakness more central to the entire identities of the reactionary "fan" grift circuit than being mocked. It's part of the reason why people so close to them backlashed hard to "weird"

You see this work on indie projects and with more in-tune and self-confident celebrities: they will when pushed retaliate by belittling the source that is whipping up a crowd against them. The crowd moves because they look up to the creator who sent them. If they're laughing instead? It's over.
