My thinking was:
Retail customers will be either too new to things to have developed that strong a preference, or will be experienced enough to find a way to re-enable their preference.
In a business world, the admins will decide. The employees might care at first, but getting the job done typically outweighs the preference for how, and they will train themselves up on the new system through lack of choice. (And as happened with me and Linux, come to prefer the new system despite an initial dislike.)
