I think that it's not so strange, seeing that you have to fork over lots of $$$ to get your hands on hardware that would run Solaris/HP-UX/AIX/etc, plus licensing fees. You can't easily rent a cloud server for an hour to play with it (with some exceptions, like SmartOS on Joyent). The high barrier to tinkering reduced proprietary Unices to expensive niche environments that are willing to pay lots of cash.
