I'm kind of confused by Web 3.0 - it's supposed to be hosted by blockchain and the blockchain is supposed to be hosted by people's computers in a peer-to-peer manner? How is this different from the old (and rightfully hated) practice, when video game companies hid torrent clients in their updaters and seeded the updates from people's computers to cheap out on BW?
