It’s simple. Nostr is a protocol, not a platform. It’s censorship resistant and permissionless. It’s the only place that allows Lightning users to react to messages by “Zap” instead of “Like”. The possibilities are endless. Check out Mutiny wallet. They added connectivity to Nostr, so the wallet works just like Venmo. Telling people to join a protocol is very different than telling people to join a centralized platform. It’s like the difference between promoting commodities vs unregistered securities. One is ethical, the other not so much.
