The entitlement is to stop malicious apps from listening to all of the mDNS beacons coming from devices on your network. It doesn’t stop you listening for/advertising specific named services using the NetService API, and it doesn’t stop you from sending/receiving unicast traffic using regular sockets.

Things like this don't happen at once. But we're slowly getting there.
