Work on your reading comprehension... The card companies charge merchants for transactions. The merchants raise their prices to cover those transaction costs: For a very long time (and still, in a few places) it was against the card company's terms of service to have a card usage surcharge. A very few places now have 'cash discounts' or don't accept cards at all, but these are by far the exception. As a result, /everyone/ ends up paying for credit card rewards, even those who don't use credit cards.
