It came from OSF, the Open Systems Foundation, which was easily the most
arrogant organization I ever dealt with. I think they were disbanded as a
result of a lawsuit involving restraint of trade, or monopolistic behavior,
or a cartel, or something along those lines.
OSF stopped developing and shipping reference implementations of software
when it merged with X/Open to become The Open Group. Doing that (and
shutting down their Research Institute) was the price for getting Sun to
join; they didn't want other programmers competing with them. ( was
technical lead of OSF DCE at the time of the merger, and left when it
became clear there was never going to be any coding there any more.)
