These large international payment processors, with their almost mafia/cartel-like rules and influence, have a long history of being used by powerful entities do enforce policies that would otherwise be (and in many cases actually are) illegal.

Their behavior certainly goes way beyond their legal mandate, if not in the USA then for in other countries. Certainly arbitrary, within international context all but certainly illegal. Considering the impact that have had around the globe with their abuses, arguable even covert state terrorism.

However, they are essentially untouchable. Any substantial threat to these companies will have several huge economies instantly through all their persuading power at whomever may cause pose that threat. I don't see that changing as long as these companies are such a convenient tool, in a system where literally everything is ruled by capital (how conveniently).

But the system will erode itself, step by step. Until it does come to a collapse. Good luck with that day, for I hope to not live to see it happen (it won't be pretty).
