How so? Folks who care about decentralization can use the menu, no? A common theme in the comments is that most users do not care about decentralization and don’t want to have to pick a server. All that scares them away to centralized platforms like Bluesky and Threads. Even a big centralized fediverse server is better than yet another walled garden they can’t easily migrate off of.
Let’s say I was on a giant Mastodon instance. And they defederated. At that point, would I be able to easily migrate to a smaller one? Or would I have to start up from scratch on the smaller instance?
