He wouldn't have admitted to making a mistake unless the negative press and outrage from C&A members pushed him to do it. It isn't as though Mr. Goldstein was sitting around the office last week and suddenly thought "you know, maybe we went too far with the changes". It was driven by the fear of losing members, and perhaps by more than a few cancellations based on the initial changes to the program.
Regardless of the motivation, I think the revised changes are reasonable. I never said the crowding issue was not valid, just that they had gone way beyond that problem in their "fix". I wish to note that Gold members will still lose the right to attend the C&A party, and instead just get a shout-out from the Captain at his new cash bar cocktail party. A new aspect of BYOB.
