they don't need to do anything that drastic. They literally need to do one straight forward thing. Force Twitter to open up their API and let people build a bridge to ActivityPub.
Hell Elon could do it if he is serious about decentralization.
At the same time at least he is greatly incentivised to get rid of car emissions, which is good enough reason for me to side with him instead of other people.

Personally I don't understand why, the negativity and the assholes are already there but maybe in lesser numbers.
What are you trying to get out the use of social media? To me, it's conversations with interesting people in a pleasant environment. I'm getting that from the Fediverse.
Unless you're a brand that uses social media for marketing purposes, I don't understand why it's sol important to use the big brand platform.
I kind of suspect the answer is going to be something like "the people I want to follow are on there". But there are equally interesting people on the other platform, it's just that you are not familiar with them because you're not on that platform.
Also, there is no need to switch completely. Follow both and perhaps you'll start paying more attention to the one that is friendly and not driven by engagement.
