Wero is not “something the banks don’t control”. It’s a SEPA-based standard, implemented by the participating banks. It originated with Dutch/Belgian technology and banking markets and Germany and France joined because their sorry asses didn’t have anything better so it’s a pure upgrade for them.
EuroPA is trying to work with fragmented markets, Wero is trying to establish a new standard. I fail to see EuroPA as anything other than a stepping stone to an eventually unified standard. Having a single currency but noeasy and practical way of spending it in a Austrian or Spanish online shop without going through American banks is an absolutely bonkers situation.

The EPI is not a German governing body. It is a partnership of banks who decided to implement Wero. All of them had to work to support it in addition to their existing systems, though it is not exceptionally hard because it’s just a frontend for SEPA. If Spanish banks want to provide Wero to their customers then they’ll join the EPI and have the same say as everyone else. But again, it’s just fucking QR codes that translate to “make an instant SEPA mandate to send X € to Y IBAN” so I don’t understand what there is to be scared of on a technical level.
I don’t understand the point of fragmenting the Eurozone for the sake of fragmenting the Eurozone. Integration is in the long run more complex, expensive, and less user-friendly than standardization. What is so good about competing solutions that they should not eventually be replaced by a common digital payment system?
