I predict that this will absolutely tank the sponsorship for projects that are not US-centric. But maybe that's the intention here???<p>In Germany, most people don't have a credit card because you don't need one in daily life.<p>Instant payments to friends? Giropay is free.<p>Buy stuff online? PayPal, Giropay, Klarna.<p>Send money to other EU countries? Every bank account supports SEPA, which is free.<p>With that in mind, nobody is willing to pay $50 annually for a card which then charges 3% of every transaction, because there are good and free alternatives. And I don't think anyone will create a CC just for GitHub. Let's hope Microsoft will think this through and offer sane alternative payment methods (like SEPA deduction, the default for recurring payments in Europe) before removing the only non-CC option.
