Shopkeepers don't want it, but fear they must if big chains start offering it, just as online shops feel like offering it is unavoidable due to the popularity in certain demographics. The financial watchdog doesn't like Klarna, and is increasing scrutiny³.
If Klarna has trouble marketing their value, then that at least is good news, but not unsurprising given the spate of attention it received over the last two years.
1: So much for the ethical side of Adyen (e.g., https://www.adyen.com/impact sounds hollow when you partner with loan sharks).
2: Some people are quick to defend Klarna for offering people a chance to buy their necessities with what amounts to a payday loan, but that is bullshit. Klarna predominantly is not used for daily necessities.
3: Klarna now has to state that they are offering a loan in the Netherlands where they are available as payment option, with the mandatory "borrowing money costs money" tag-line.
