You have to use send for unconnected sockets. Saying it can't be used for unconnected sockets is nonsense. The system would have no idea where to send the data to.

Furthermore, UDP sockets can be connected. Connecting a UDP socket specifies the default host+port for sending, and it specifies the only host+port from which it will receive.
