In fact, this move is largely to displace overbooking to a new mechanic. Now why this is a problem: Want to book a necessary flight 3 months ahead of time, shop for the cheapest fare, amd then find out a week before your trip that you've been bumped to a later flight (posssibly missing scheduled activities) because a last minute customer wants your seat? Unoversal adoption of United's model would make this common place (at least as common-place as overbooking is now).
