Practically no one in the world who accepts payments for their online business directly integrates with visa or Mastercard. It's all 3rd party companies who integrate (because it's fucking hard and tedious) and then resell it in a nice easy package.

In almost all cases, any talk about payment processors, is them, not visa/Mastercard.

I remember seeing a graphic that was about every layer of companies that are interacted with when you use a credit card. Must have been at least like 6 layers of companies each taking a fee from a company that took fees higher up the chain closer to the consumer. Similar when I read an explanation of, when you buy a stock through a company like Fidelity where is the stock actually held and that was layers of public/private companies/corporations

True. Collective shout targeted visa, mc, paypal and paysafe. I guess it's possible the game storefronts acted due to concerns of one of them.

In online stores Visa and MC are the big ones. If we exclude China, Visa and MC make up 90% of all online purchases worldwide. For online stores they are the two players who matter. Losing one is a significant loss of revenue, losing both will kill the store.

All of those devices are child companies of either Banks or Credit Card companies. Or, like Square, owe their continued existence to banking and wall st firms dumping cash on them.

The one outlier I know about is Canada's Interac system, which was started by Canadian banks, but now is its own thing
