Valve is basically a small business one bad Monday from going bankrupt compares to payment processors.
Few quick searches around the internet says that (measured by revenue) Mastercard alone is roughly 3 times bigger than Valve. So even if Valve is pretty big player it’s not even close on major payment processors. And they’re not playing on the same rules either, any payment processor can vanish payments for anyone with just ‘fuck you, that’s why’ -reasoning buried in their contracts. There’s almost no one who could afford to fight with them even in theory and much less in practise.
