Is this a troll post? There are multiple shortfalls that make Mastodon harder to use than twitter for the average user. Here's a great Op-ed explaining them: https://arstechnica.com/information-technology/2023/06/op-ed-why-the-great-twittermigration-didnt-quite-pan-out/

The tl;dr is that decentralization is no selling point for the average user and if the experience using Mastodon is any worse than using Twitter, people simply won't switch. And there are numerous big issues with Mastodon's usability that make it inferior to Twitter: That there is no proper way of exploring creators, that following creators is a hot mess, that Mastodon instances can block each other and thus make it impossible for their users to interact with each other. All those drawbacks come from being decentralized, while the only positive, not being ruled by a billionaire man-child, clearly doesn't bother people as much.
