The services credit card companies provide was just pushed a layer deeper to the issuing banks. The EU didn’t magically make the costs of running a payment system disappear, it’s just sleight of hand. They also pushed costs onto consumers in the form of assumed risk consumers take on when making a purchase (thus all the 2fa etc to reduce this burden).

Oh and it goes without saying that rewards programs disappeared entirely (I am not opposed to outlawing “rewards” programs)
