I have to hardily disagree here. @Club Orange adding their events is a huge win regardless if the host publishes or not. It seeded a huge amount of data to nostr that just wasn't being published before. They could drastically improve by letting their users give them their npub within the settings of @Club Orange and if a user has a listed npub use that npub as a p tag to show them as the host but that doesn't diminish that it was a huge win regardless. It doesn't really matter who creates the event. Most nostr livestreams aren't pubished by the actual streamer. They are determined by the p tag of the listed event host. As for managing two lists it would be easily for OPA to just import the same public nostr data into their own DB to let their users manage their event directly in their own ecosystem over OPA+nostr.
