As their 1/19/19 restriction stands, Disney is claiming the right to differentiate ownership based on both how AND when an owner bought their property. I would argue that this restriction combined with the ability or inability of Riviera owners to trade into the 'original 14' breaks any reasonable definition of DVC 'owner' or 'member' of the club that allows for trading - we are all Schrodinger's owners neither in the club nor out of it until Disney wants to see us in a certain way.I get that they can change the perks associated with membership based on where you bought (or likely even where you own) but I don't understand how they can start to distinguish a difference in members based on how they acquired the points. Does that mean at some point if you own SSR you are no longer allowed to trade into resorts at 7 months, but only at 6 months because they don't like you any more?
That said, my understanding is that the easier change would be for Disney to go in the other direction - retaining 7 months for 'everyone', but restricting resale owners to 8 months while continuing 11 months for direct.
