People use separate “loyalty cards” which are a pure data for discounts play happily enough. The only reason such cards have become less popular over time is Mastercard, Visa, and Amex have rendered such products redundant. At this point you can also 99% of the time pay cash and efforts to change this face significant political resistance as being discriminatory to the poor/unbanked. I think the argument “why don’t you just not use their products if you don’t like the deal” is a shockingly good argument… for now. We can revisit this issue when society truly goes cashless, but for now, not the hill I’d die on. Mastercard will cry bloody MURDER before they let go of this gold mine. If anything I find the interchange fees and the virtual monopsony the credit card companies have to be more scandalous.
