Answer:
Because they don't meet the definitions of consumer in some of the regulations - - Regulations E and DD leap to mind - - they aren't covered and should not receive the consumer disclosures. On the other hand, they will be covered by Regulation CC and by the "zero liability" provisions of Visa/MasterCard rules. Some banks deliver the consumer disclosures nevertheless, with a disclaimer stating their restricted scope.
