Side note: Looking at their job listings I don't see any engineering positions (with the exception of a security engineer which is a grey area in a bank IMO), only managers and business roles.
But you just answered your own question.
Wero is a money extraction business that secured European Commission support. There is no engineering nor payment system to it.
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.
Wikipedia gives an overview by year.
As for the axe, I have no personal interest.
