If X were simply a store, boycotting would be doable, but it isn't and therein lies the problem. It's like a country where people live/work and have their engagement turned into money for the country. :/ To be clear, I never used X, but I know of the struggle. The other thing... if you leave such
a group without opposition, the platform could become an echo-chamber that emboldens. It gives the illusion that everyone agrees & that they're a majority. That could also be dangerous. I am sorry I don't have any answers for how to fight, but ... maybe some answers on why good ppl haven't left X.
