Yes, that's the bad thing. I wouldn't mind that they prevent me from using their service if it was just "yet another service". At the other hand, they did actively try to gain market dominance, and they have succeeded to such an extent that it's becoming hard to be without Vipps today - whatever side of the table one is at. We did this fundraising fleemarket event for one weekend, and Vipps had technical problems during three hours of it - we lost significant amounts of turnover due to that, those three hours were quite important for us, and although most people visiting our fleemarket has indeed been smart enough to carry cash with them, it's becoming abnormal with cash.
I have a Polish friend that is sometimes doing street business, like selling sugar spin or transporting people with his bike taxi - and he's also having huge problems as he, as a polish citizen without residence in Norway cannot have a Vipps account. At the other hand, I can hardly think it's legal to do such business in Norway without registering a company and having all the permits in order.
I think it's pretty bad in itself that they are getting such a market dominance, and it's even worse when they can blacklist customers as they like - and even having downtime on their service every now and then.
I think the whole world is moving away from actual cash.. even here in third US it's debit cards .. ...if you don't take them you lose a lot of business.. .the cashless society is quickly approaching
It's just so very much important to avoid monopolies or duopolies ... or any market actors having too much dominance. I seriously got my eyes opened when two companies could just decide "we don't like Wikileaks, and will no longer serve this company", and whoups ... 90% of their income vanished.
Some 20 years ago I would expect Norway to be one of the first countries, as we were relatively early adopters of debit cards (and our national standard BankAxept - also a monopolist, but at least very much cheaper to use than visa/mastercard). Today I'm happy that we're mostly still able to use cash here in Norway (even if it's quite rare). In Sweden one cannot buy beer in the pub without letting Mastercard/Visa know all the details. I observed this sign in Stockholm late Friday night:
