Those of us who do support on systems from many different clients really don't wonder why they still exist.
HURD is one thing; we don't really wonder why it's stillborn. OS/2, or more specifically eComStation, is something else entirely. OS/2 has a history of commercial support, which means it's also got a history of applications with support. Support means that people used those applications, on the OS, in a business capacity. Think of OSes like: SCO, DOS, and yes, OS/2.
Just because the OS, and application, support goes away doesn't mean those applications aren't still needed. There are a LOT of applications out there which were written one-off, for a single client in a specific role. The companies that wrote them may not even be in business anymore, but the application still works and the the cost of
So people are running their applications on legacy operating systems, sometimes on some pretty janky hardware (I once saw an old box with IDE controllers on a proprietary IDE RAID controller - with half the RAID consisting of CF cards on adapters). Maybe they've managed to virtualize the platform, or partially virtualize it (such as when there's a hardware platform to the application, requiring COM port bridging to the guest so that a USB to COM adapter can be used to interface with a proprietary reader/etc. - you get the point).
No, it's not an ideal business scenario, and there are certainly situations where a lot can go wrong, ruining your day. But There are a lot of these companies, which means there's a special use case for support. Or just in-house people needing to upgrade things to keep as much of their stack compatible as they can.
So yeah, there is still a need for such legacy platforms. Just because it's not shiney and new doesn't mean it's lacking a valid business case.
