Actually if you look at banking/ finance sector and any company that is going in for certification one of the criteria states that you need to have a licence OS.
What does that even mean? Even if you build the whole shebang from scratch, it is still licensed, since the various open-source licenses (GPL/LGPL, Apache, Mozilla, BSD...) are valid, enforceable licenses.
I think you mean "...you need to have a supported OS" - in which case, it is sufficient to support it in-house and not rely on third-party vendors & support providers. Linux allows banks to follow this path (and I believe HSBC actually does this).
