Unix is proprietary in the sense that hardware manufactures of computer
systems have to build kernels and drivers that operate on there
processors and peripherals. Even companies like SCO that write code to
more generic hardware have the right to copyright their work and sell it
if they wish. BUT this has little to do with the classic definition of
"open systems." (see
Microsoft is a member of OSF which means they are committed to providing
interoperability between systems at a software level. For example - MS'
C compiler supports a standard set of function as does Sun's and HP's.
