Yep. Meta have even announced that they will allow people to migrate from mastodon to meta’s platform.

Meanwhile mastodon have no such feature for migrating from anywhere else to mastodon. And you can bet it won’t be easy to perform the migration away from meta.

More deeply, it seems to me that the fediverse hasn’t really appreciated that it needed to find ways to work together and not reinvent the wheel for every new platform or UI. As a result, its killer feature should have emerged by now but hasn’t, arguably at all … namely the whole fediverse and all its various platforms becoming one giant “actually meta” platform. This requires good interoperstion and good standards etc. But once you’ve got it, any new feature or idea anywhere can contribute to the whole and stay behind the reach of any big corp’s abilities. Instead, the fediverse is a bunch of separate and small independent hackers trying to clone big social platforms without much help and now in a race to stay ahead of big corporations.

If the fediverse dies, failing to create modular and composable software will probably be the ultimate killer.
