After going through a few threads on this, I am coming around to the notion that a good bit of this issue is with DVC members that live in Southern states not named Florida. For members that live in states like GA, SC, NC, AL, TN, MS, or LA, WDW is a drivable trip, which, IMHO, changes the visit calculus quite a bit. In fact, for many in South GA or AL, they are actually closer (sometimes by a good bit) to WDW than someone that lives in say Pensacola, FL.
We have friends that would go 5-6 times per year, often just for long weekend getaways, etc. Without APs, those things are a thing of the past for them. Now we all tend to have more points than we are really using and many are just now coming to that realization.
