The US has the Fair Access to Banking Act trying to do similar things, but it's been stagnant for 2 years.

This bill places restrictions on certain banks, credit unions, and payment card networks if they refuse to do business with a person who complies with the law. Restrictions include prohibiting the use of electronic funds transfer systems and lending programs, termination of an institution's depository insurance, and specified civil penalties.

Banks and other specified financial institutions are allowed to deny financial services to a person only if the denial is justified by a documented failure of that person to meet quantitative, impartial, risk-based standards established in advance by the institution. This justification may not be based upon reputational risks to the institution. Banks may also deny services to a person who engaged in rude or harassing conduct toward an employee of the bank.

The bill establishes the right for a person to bring a civil action for a violation of this bill.

That is possible, of course, but European companies and citizens are less crazy so far. No guarantees, but the chance is here. Plus, more competition might force older processors to drop irrelevant to their work arbitrary stupid limitations.

Yes, but the american payment processors are the ones in power and actually carrying out these punishments. They could've simply chosen to ignore that group and nothing would've happened.

Sorry about them!
