Of course, this makes UA/CO uncompetitive in that regard.
Keep in mind though that:

b) UA also allows updgrades with SWUs form non-deep-discounted C (UA term)/J (CO term) to F, another benefit to the high-revenue flyer.
What we may be seeing is the shifting to a program that is designed to primarily benefit the highest-revenue flyers....basically a MileagePlus-ization of OnePass.
