Rewards aside, credit card also offers things like extended warranty, travel insurance, chargeback protection. These things makes them invaluable to customers. I use my credit cards for everything because it’s strictly better than debit and it works everywhere.

Accepting credit cards is a net benefit for merchants, even accounting for fees due to increases in volume. This is just greed. They want access to the network without actually paying for the privilege.

It’s not entirely one-sided, customers do pay for the rewards: My 3 credit cards are costing me 1500$ per year in membership fees.
