They should know better.
I resemble that remark if that's your definition of clueless. The best justification for mileage earning credit cards is the bonus miles for signing up. At regular redemption rates, it makes no sense for almost anybody to use a mileage earning card rather than cashback - unless you fly premium class awards. See my treatise
on the subject
here (at post #3).
It's clueless not to use some kind of rewards card. Whether it should be a mileage earning one is a completely different question.
