It's easy to see why. Both Swish and Vipps is part of EMPSA. In Sweden, everyone uses Swish. Vipps (from Norway I believe) wants to expand to Sweden but no one is using it since it's not compatible with Swish. So making it compatible would potentially hurt the business of Swish.

Regulation is needed. Otherwise it will never happen.

If EPI / Wero reach a critical mass then hopefully this will change, as non-Eurozone countries will have a direct interest in making the local mobile payment solution accept the one used by an area of 350+ million people.

Then the EPI protocol could become the least common denominator and you might be able to use Vipps, Twint, Blik... in Sweden? I believe similar scenarios are happening in Asia around Alipay and UPI, for instance I think I can use the Korean Kakao Pay on a payment terminal in Japan, because both sides are compatible with Alipay+.
