So the question is, could both Valve and Itch take on several payment processors, and choose which game on their store goes through which processor? Or would porn-shy processors have blanket rules saying your whole company can't have any porn in the same store, even if it's locked away, even if you use not-us to process payments for it?

And secondly, let's say Valve moves to a porn-friendly processor (Itch has said it's looking for one, not that it's found one). MasterCard clearly has a rule, right there in black and white, saying don't facilitate this particular type of porn. How do you think it will look if for any potential processor, and MasterCard, if Valve switches processor and continues accepting MasterCard payments for games in direct contravention of MasterCards's given rule, while the world's press, and the angry lobby group, is watching?
