If you don't pay! You don't get to play! Nostr is not for freeloaders. Zap Stream is still extremely cheap. It cost to stream on the cheapest plan, 0.01 sats per minute. If you stream for 1 hour, total cost is 0.06 sats, not even 1 full sat. Not allowing free streaming keeps the bad actors away, and gives a tiny profit to the developer. I think it's a good decision.
