It’s not common knowledge. I don’t point it out often because people think i’m just crapping on primal or something, but it’s a huge difference on how their client works compared to other nostr clients. It’s too centralizing for my taste. until there’s a world where everyone is running their custom relay, but thats not even spec’d

Not to say their approach can’t work, its just requires more money and maintenance to keep alive. Most other clients don’t need any supporting infrastructure: they will keep working after the developer dies, runs out of money, gets bored, etc.
