People act like this is some spiteful thing he's doing in order to just post edgy memes or have a 'private' social media for himself. Twitter, despite being a toxic place the majority of people avoid, brought in over 5 billion dollars last year. If elon removes bots, welcomes non-extremists back on, gets comedians and entertaining accounts back on board and lets people say what they want instead a bot army of shills…
Twitter is so fantastically successful because they've created a platform that both feeds their users a constant stream of enraging content, and more importantly, incentivizes the creation of content that's enraging to someone else. In the process they've managed to mold almost the entirety of mainstream public discourse into an endless supply of hot takes, sick burns, and us-vs-them polarization that results in Twitter being an essential tool for anyone who wants to participate.
If they get rid of the rage bait and toxicity, then people won't need Twitter anymore and will move on to whatever new platform provides it for them.
