federated Exabytes of content
Unless you have special affection to YouTube moderation, this has to be done even if you want to believe it is hard, but that being hard is completely untrue.
Federated =/= unstructured p2p network
A host can be a big instance in fediverse, the others can host another instance, can visit the big instance if it has the bandwidth, but not necessarily host the data (which is the case for unstructured p2p network, where everyone does the same task). As long as it is free software, both the host and user skip the hassle of adopting different interfaces.
The fascists think they die happy.
