One has to choose between what you say (which makes a lot more sense), and what they do.
DRK masternodes don't work at the moment because the node payment system caused a fork last week. Do I need to link you to the DRK dev's official testing topic where's he's trying to sort it out?
No, DarkSend works, you can use it right now, only the payment of the masternodes has been postponed to mid-June.
PS: No FUD intended it's just fun to deduct the real sender from a mixed transaction.
