Why Monzo should be open source

A reply to the "Is Mondo open source" forum thread from 2016:

I know this was years ago, so I’d love it if, but I’m not hopeful that, Monzo’s attitude to Open Source might have changed.

This was such a painful thread to read. Yes, it’s unthinkable that a regular bank would open-source their code, in the same way that it’s unfortunately unthinkable that they would have reduced transaction time if they hadn’t been forced to, or that they would use standard 2-factor authentication methods. The banking sector have various delusions:

  • firstly their security needs are different from (greater than?) the rest of the tech industry, and so they need different methods
  • secondly that their use cases are legitimately so much more complicated, so they can’t possibly use the same tools and practices as the rest of software
