I see all the changes they've made so far as business changes. They seem to only change things that affect their bottom line.
If they feel allowing people to dress how they want and to have facial hair would result in higher donations, they will do it.
But I agree with others that once they relax the personal rules that dubs live by all bets are off and that their control using the BITE model won't be able to keep going. I feel that dubs love to be martyrs and pride themselves on standing out in certain ways - dress and grooming being one of them.
