It might be worth noting that when an enemy vampire dominated the PC barbarian with the orders "Kill them!" his fist instict with another downed PC was to CDG because his order was to kill. These are the kind of people I play with. 
There are lots of situations where CDG is a good idea. Curative magic mid combat can take a seemingly downed opponent and turn them back into a threat. If you finally just took the tank down, don't move onto another, CDG so that he doesn't get back up. The PCs have been on the other end of this enough times to know themselves, and its the most common. The second most common I've run across is the helpless opponent. When a ghoul paralyzes you, you better bet the next thing they're going to try is a CDG in normal circumstances. A held opponent is also CDG fodder.
It's not unfair. It's a good tactic. Noting wrong with the CDG. Might as well complain about NPCs casting disintegrate.
