Speaking for @PUBKEY here, the reason is that we don’t want to deliver a subpar experience for Nostr. Doing livestreams is a commitment of resources for a very small team. Incorporating zap.stream into our process is more involved than just adding a stream key to our Restream account like we do with Rumble and YouTube. Nostr is highly interactive and requires attention on the chat and the zap goals, etc. while not neglecting other aspects and details of the stage event and the audience. We want to get it right.
