Better question is why blossom when there's BitTorrent?
I've heard blossom is faster with initial response time but then I did some more testing to see how fast BitTorrent can be and it seems plenty fast enough to me

Oh .. I have nothing against Blossom or Torrents .. .. my point was from a creator standpoint ... If you are a show maker ( aka video podcast - whatever that means :-) , then you got to be on youtube ... that is just the reality ... same for the musicians - they need to be on Spotify to pay their bills !
The approach at #nostr should be to help creatives bring their yt and spot content to nostr ... asking them to upload their stuff on nostr media servers (again) is a non starter ! ..
Besides .. if the goal is censorship resistance .. then nostr must provide censorship resistance against the big platforms.. not against their own Primal or Nostr.build :-) ..
The way I vision this is - when a creator is uploading content to major platforms , they should get an option to replicate to nostr media servers .. and also an option to bring past content for v4v .. zaps are a great incentive ... but the work should be easy ... I mean that is where dev effort should go ..
