I agree that there is nothing to fear per-se about a Kinetic rope. They should always (in my view) be used in conjuction with a bridle, I never trust a single anchor point where there is that level of energy involved.
Also, a Kinetic rope should not be used routinely, but rather as a means to recover a vehicle where other methods have failed.
Kinetic ropes, as with winches are dangerous when used without the care and respect they demand.
