No, the idea is to have more endpoints (streaming servers) available to select from when you want to stream to nostr. zap.stream is just a web interface showing nostr streams. Like every nostr app just shows rendered JSON from relays. Having more endpoints (in different geo-locations) would not only make attacking live events a lot more complex, it would also allow people to stream via endpoints closer to their own location.

At the moment the only streaming server is located in the EU which means that many people have had issues streaming on nostr anyway simply based on their geo-location and their added latency to the server. More endpoints fixes that too.

Basically with more endpoints you "pick your provider", top-up your balance with that provider, get your stream key from them and go live. If that provider ever has any issues, you simply buy credits from a different server, change your stream key and you're live again.

I'm putting up one server in Germany which wont cost much unless it's being used and if it's being used the users will pay for the bandwidth. Just like blossom servers.
