Yeah, it literally does everything OP described.

It reduces the servers cost massively by having a video player, that simultaneously uploads the stream p2p to other peers. So theoretically, the server only needs to stream every video to one or two peers at once, regardless of how many people watch it.

And storage cost is reduced by the federation, so every instance can only host a small selection of videos and share it to the larger network.

No, it is not. They still get billions of American taxpayer money
