OSX is still a proprietary operating system no matter how many qualifiers you want to throw out there. Apple's relationship with your freakish "community" is testy at best. You're really going to hate them when the lawsuits against these open source hackers start actually getting filed.
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?
And no shame either for taking me out of context to claim I said something contrary to the plain intent of the sentence. I'm impressed.
