Content-addressing together with P2P and extra paid relays for those who really need it. In terms of "superstars" sharing content, if they share their image which is content-addressed and can be fetched from anyone, it's enough that one peer shares it with three others for it to be reliable enough in practice. Content like that is also usually just relevant because of recency, so large swaths of people try to access it within 24h, after that the news cycle already moved on so won't be fetched much after that.
