It's amazing how long this has been on the front page. Are people upvoting as a "hit" against the EU wanting out of Visa/MasterCard? It's certainly interesting timing
edit: It seems Viva primarily is a neobank, not a payment processor. I'd never even heard of it until today. It's tiny compared to Revolut, Monzo etc. And tiny compared to an actual payment processor eg Worldline (French, 18,000 employees)
