I happen to work in a bank in Scandinavia, and you're both sort of right. We did at one point provide "open banking APIs" although we only ever approved one partner to use it, and have since shuttered it.
The truth of the matter is that banking is horribly entrenched. Actual business decisions are mostly driven by arbitrary considerations of which laws to follow that day. Although we provide a ton of functionality and business capability, we are still woefully behind on any sort of compliance measure, not because compliance is hard or impossible, but because nobody is actually critically examining the systems.
The problem for the "neobank" is not one of building technology to catch up. It's in cultivating an image where they are seen as systemically critical such that they will be afforded the same leniency in policing that the established sector already has.
