Hold up here. Yes I know about the GNU thing, but what about Linux kernel and many of it's programs? I'm just being technical here, not trying to discredit others. if Linus Torvalds hadn't of gotten the idea to make his own OS, Linux would not be here.
I wanna add my two cents about Datacide.
When he says he wants to combine the best parts of OSes, he could very well mean design principles, not stealing source code.
Also Datacide made a terrible mistake in his ideology. It's ok to want to be bigger than Microsoft, but Datacide probably fails to grasp how truly bad Microsoft is. He sees success, we see bullshit. Also, Microsoft didn't get where it was with OSes and programming languages(this is probably moot point anyways), it got there with one fuck of alot of luck and the consistent usage of dirty tricks. Datacide probably doesn't get this either.
