If it's really the case it's a real MINUS for us in northern region in winter time when stuck in the snow: With DTC ON you're not able to move because if a wheel start spinning... and it will... power is cut off so you'll not move for sure and with DTC OFF and an open differential if a wheel spin free... and it will... even if the other wheel could found / give some traction this one will not help because only the one that spin free (on ice for exemple) will rotate. Comclusion: One (in ours northern countries) will be better off with a car e/w LSD than with DTC That's my understanding, I am right ?
