I don’t see them revoking lifetime status from anyone who has already earned it. They lowered the requirements earlier to be more competitive with SPG’s program. The marginal cost of having life time platinum and gold members is outweighed by getting them to stay when they are not traveling as much. They benefit when people with lifetime status tell others about it. I still remember an older couple talk about their lifetime platinum status several years ago. The husband had over 2400 paid nights, and this was before credit card nights were common.
