> For smaller entities it's a PITA to have to manage a separate additinal contract, and it costs a lot more for the merchant, when virtually nobody only owns an Amex.

I completely agree on the cost part for AMEX, but how do you mean it's a PITA to accept those cards? It's usually as simple as enabling an option with your card payment service, not very complicated at all.

Visa/Mastercard is usually a contract that is bundled with your PSP, where Amex needs a separate contract merchant by merchant.
