Personally I think that if there was like a central link/front end to access everything and then have each user be able to have a recommended list of instances/hosts to access would be a more user friendly solution and a better solution for search engines. I know the fediverse is about decentralization but having a central front end and decentralized back end seems easier for new users. And then for the back ended hosting aspect each host would be able to manually pick which instances or communities to host and mirror. I'd like to hear your ideas since I have no idea what I'm talking about.
Unless you physically own your hardware and connection, all of this is moot anyway.
Any time you're spinning up an instance on cloud-hosted solutions, you're by it's very nature putting everything on someone else's physical property.
This is an issue I wish was discussed more, because Federation helps ameliorate certain problems with the modern internet, but it doesn't address how much of the physical hardware and networking infrastructure is privately owned and operated.
Seize the means of computation.
