I almost get the impression that wants and needs are confused here... Some people didn't want 10 different commercial types of UNIX, but some people did need a specific type of UNIX.
They 'needed' them because different vendors were using producing hardware that only worked for one and were deliberately writing software so it wouldn't work on the others.
