The "proprietary"nature of the updates is a smokescreen being poorly used by Ed French to skirt confrontations with upset Marriott Rewards members. They spill a very small(50 of 350 plus)percentage of the "ok"catagory changes and yet hide the rest.This very shady aproach is telling me to expect massive devaluation of MR points. As they are "our"points earned with "our"money I believe these changes should be disclosed.By not disclosing them Ed French is demonstrating how little regard Marriott International actually has for its best customers.The response on Flyertalk by the Marriott"concierge" just adds insult to injury. I have always played fair with Marriott despite my growing irritation with them and the devaluation of a once fine program by Ed French. Maybe that needs to change.
