But there's another side to this: a feed composed of things from people is *fungible*. Theoretically, you could uproot that feed from one platform and settle it in another one - if everyone you follow on Twitter set up an account on Mastodon, you could use a tool like #Movetodon to refollow them there and get the same feed:

A feed that is controlled by a company using secret algorithms is much harder for a rival to replicate.
