Why, Maistre Gracey, how very kind and gracious of you to point that out!

I'm not sure that Fairfield has any interest in being DVC. These are very different companies with very different agendas (other than both seeking our hard-earned $$$$$, of course).
Disney's market is a very upscale, Disney-focused community, who enjoys the exceptional quality of their resorts and who are pleased with the very specific locations of the Disney resorts for their membership usage. This market enjoys and appreciates the upscale alternative options that DVC offers in the way of top-tier hotels, B&Bs, etc.
Fairfield's market is decidedly closer to middle/upper-middle class (and perhaps a bit older?), who enjoy the family-friendly, laidback atmosphere at most of their resorts and who are pleased with the extensive list of FF's USA resorts spread out across the country (and growing rapidly). This market enjoys and appreciates the diversity of destinations and alternatives (including Warner Inns in England and many, many options throughout the cruise industry) that FF offers.
FWIW, just as Marriott can provide a very nice complementary ownership for many DVC owners (including the ability to trade into the Marriott near
Disneyland Paris), FF may provide a nice complementary ownership for some DVC owners (including the closest timeshare to the California Disney parks - Dolphin's Cove, which borders Disney-owned land slated for likely development as a Disney water park). Many FF owners also use the RCI Enhancement to FF (like "RCI Points") features for hotels, airfare, car rentals and cruises.
Just a thought worth considering for some DVC members, who may have been looking for a different points program to round out their timeshare ownership.

JMHO.
