Old Dutch banks and their Belgian suckers, mostly. You can see a list on their website.

I am not deep into this, but I heard multiple times that the choice of the pan-european payment system was largely political and technnically suboptimal. Old Europe pushed for the aging iDEAL against a much more advanced Blink, so Eastern European banks led by Poland left the consortium.

In the end, iDEAL rebranded as Wero was dead on arrival because a successful system needs to be supported by everyone.

Others joined quite recently, indeed.

Wikipedia gives an overview by year.

As for the axe, I have no personal interest.

I have no idea what you are talking about. I have been using Wero for a while in France and it works just fine and is completely free. It's basically instant bank transfer without any fee or limitation on how many you can do.
