Name one dominant payment system worldwide that doesn't? Banks are proprietary, credit cards are proprietary, paypal, crypto is all proprietary.

Nearly all of cryptocurrency is fully open source and properly FOSS

You mention crypto; it's not a dominant payment system, but nor is it proprietary; there are open source wallets and the blockchains are open source.
