I don't know why they did what they did, but that is I report I would like to see even though I disagree with your general take that Nostr is fundametally centralized. Keep pushing.
Peter was very public about seeing serious issues but I haven't seen him consider the outbox model. I've seen some project - was it some git replacement? - using some DHT to store the outbox relays of users and with TOR in the mix ... how is nostr not decentralized? I don't get the criticism and thus I don't get the need to spend $20k on exploring problems that are not problems yet. Yes, nostr is dirty and naive in its approach but it still might actually work.
That's what I like about it. In theory it sucks, in practice it works. It's like e-mail. Super bad idea to do it like it was invented, but we found a way to use it daily and it just works. Overengineered designs earn PhDs, but don't have users.
