How does the federation work from a high level? On Reddit, data is stored and managed by Reddit.
How about the fediverse? If the data isn’t centrally located, what is stopping some data from just being lost at any time? Who owns the servers?
If the servers are owned by anyone who wants to own a server, I assume there will still be popular servers that get the most traffic. And if those servers have high traffic, how will they sustain that model? How do they “keep the lights on” without ads?
