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.
