RDMs via flying cost more to get now for a lot of frequent fliers, so old miles were "purchased" at a cheaper price than new ones are. If you like flying partners, there's been a devaluation of miles, but use on United hasn't changed that much - so far. As for mileage usage under upcoming scheme, looks like flexibility is going to be even more important.
