Re: Linus exhibits all the qualities of pure sociopath
If it wasn't for him, we'd be limited to Windows, and maybe what OSX would've been.
That's very doubtful. FreeBSD's origins predate Linus's efforts, and FreeBSD's itself first hit the Web very soon after Linux. Had Linus studied the History of Art instead, FreeBSD would have come into existence anyway (it was well on the way to completion). FreeBSD is pretty good.
Then there's the NetBSDs and OpenBSDs of this world.
You're also ignoring some perfectly good commercial OSes; QNX, INTEGRITY, VxWorks are all excellent. QNX in particular is quite interesting, in theory it's capable of being the basis of a desktop OS (you could use it like that back in its very early days). INTEGRITY could too, though that would be a massive piece of work. VxWorks is well and truly stuck in the world of embedded systems, but is (like the others) pretty good at what it does.
