On the other hand, Swish is fully owned by a couple of banks together. So they have full control over Swish and also over BankID, which means that they can deny people from access or if they are down then you know we're screwed. So even if it's not relying on one single company it's relying on a few companies that work together. So instead of a monopoly it's a cartel.

And as a practical matter, they make sure everyone has a smartphone firmly managed by either Apple or Google, with the excuse of protecting us from ourselves.

Those banks are under Swedish jurisdiction. Big difference.
