Rip out the open source, and how well will OS X function? Hint, it won't even boot. It'll be a bunch of useless code sitting on the hard drive.
Going back to the point, Apple was languishing until it decided to use an open source OS as the basis for its new OS, discarding its previous entirely proprietary OS. Open source can mean profit. It does not ruin the companies that use it.
So, are you ever going to fess up to your libel?
I have no problem with open source as a component. I have problems with open source when it is pushed as the only alternative, as is being done by those behind the GPL movement, as you know. They see no co-existence with proprietary software. You typically defend them, and are attempting to misconstrue my position at the moment in order to score points in for their sake.
I have no problems with Apple's process, their operating system is ultimately proprietary. Just like the DRM that is in their music delivery system. They are ultimately NOT an "open" company as you are trying to portray them, just so you can use that as leveragle to push your total open source utopia. Forget it.
