Regardless of what you can or cannot use in the EU, the fact is that if we look at our wallets, all our cards are either VISA or Mastercard, even the ones issued by local (non multinational) banks. Can we really trust that, in the future, we can use out VISA card to purchase something, even if the processor on the store end is BLIK or something else?
My thinking was to frame this not from the perspective of the stores, like itch.io and Steam, but from the perspective of the European consumer's rights being restricted by a foreign company that the consumer has no way of not using because the European banks do not give the consumer that option.
Now my question remains, is this a case for Petition because one cold argue it goes against EU freedoms, or is this a Citizens' Initiative like Stop Killing Games? Probably the later since it has a lower formality bar.
