Nothing, ostensibly. Do you think all the hot-ticket celebrities, brand accounts, political figures and self-made Twitter moguls are ever going to leave Twitter? If they do, it's because they're taking back that publishing power for themselves. If they don't... it's tacit recognition that Twitter "won". You want a TikTok-style microblog feed that nobody wants to offer. People won't ever "move over". You can either use the protocol you like with the people that interest you, or use the platform that people are on. I say this harshly because I like Mastodon and I'm tired of people assuming that things will ever 'go back to normal'. Your idea of 'normal' is giving one party universal power over everyone, and if we make that same mistake again then we deserve another Elon Musk situation.
