People turn up for the stream and they expect to have something to watch. I'm not sure about the match being a "show off" but as a dedicated spectator I'm feeling disappointed and betrayed not having anything to watch at the scheduled time.
While I'm aware that there's cost issue associated with streaming, the tournament organisers also have to take the effort from the audience into consideration. People turning up to spectate/support the players and now they're left hanging dry and feeling betrayed. Just check out the streaming site and see for yourself how many people are still hanging around exchanging chats. The administration may for whatever administrative reason cancel a match, but the audience must be catered for or they'll lose trust in the organisers.
Oh well, at least it's over. You may not have to worry about it for another year but this will leave a bitter taste in some audiences' mouth for sure.
