We have certainly enjoyed any little spiffs we have received over the years, at time of purchase people are told what is current and that they are not guaranteed and others have ended. The EPCOT lounge was at first a trial and then extended for the full year and then extended into the next year, never a permanent benefit. Park Passes,
discount tickets, restaurant and merchandise discounts, tours, parties, welcome Wednesdays, and so many others have come and gone, does not seem to make DVC evil in my mind. We have enjoyed TOW a few times by having a drink and waiting for the fireworks or a very late night snack at the end of the day when staying at BLT, if it went away it would not be the end of our world.
I don't understand the "screw job" on point allocation comment, the resort points can not increase only move around the various categories, times and areas. That normally takes into account highest utilizes and lowest in order to try and even things out a bit. We all have our pet peeves, mine is walking and DW's is lack of more options along Boardwalk late night, here some seem upset DVC does not permanently retain spiffs. If I had my choice to permanently retain a single benefit from over the years it would be the free (or even deeply discounted) park passes.
