In the article Matt Joseph especially mentions that banks are re-examining old beliefs about software and that they are moving away from the traditionally fixed position of keeping all things closed. According to Joseph, banks are increasingly looking at their intellectual properties and asking whether these add value when kept closed, or are the kind of utilities that may be opened up without losing competitive advantage.
This change in attitude among banks also shows in Deutsche Bank’s recent decision to open-source part of its Autobahn platform.
I personally think that this is a nuanced and rational approach to software licensing that all actors should consider. In particular, it moves our thinking away from the fear or gospel often heard in regard to open source and focuses on actual conditions that are relevant to your business.
