> I don’t really understand how “decentralized federation” solves any of twitter’s major issues? Scihub can host their own mastodon instance which means they have power of moderation, Twitter cannot impose whatever rules they want to.

Being federated means posts on Scihub can be seen on other mastodon instances. This allows Scihub to allow a select few users to join their instance without limiting visibility of their content as it can still be seen and interacted with through another mastodon instance.
