Thanks for the details, of which most I already figured. However, your response does not address the issue of solving content disappearing once the instance goes away. It doesn’t matter if the network itself is alive when the content itself can disappear at any time without warning.

If I am correct in this assessment, I can really see no upside besides minutiae regarding an illusion of control to established social media. In this regard, a website with a comment section would serve much the same purpose.

If twitter.com goes down, all of twitter is gone. There is no secondary Twitter server or alternative service that you can use to do your day to day tweeting without completely depending on Twitter's centralised API.

If mastodon.social goes down, c.im accounts will still be live and I'll be able to follow them through a mastodon.nl account if I want to. It'll be sad to see the toots from mastodon.social disappear, but most of the Fediverse network will remain online. By segmenting users across different servers, the ecosystem can remain alive despite the collapse of a big server.
