Pretty funny, or sad, depending on your viewpoint!

To hear some people talk, everything started with Linux, and Torvalds
is a god. Nonsense.

Even iOS and MacOS are derived from BSD, I believe. I know that MacOS
is (or has been until relatively recently, at any rate) derived from
BSD.

MacOS X is derived from BSD + Mach VM, with lots of infusions from BSD and other projects. iOS is derived from MacOS.

I think that it is more clearly expressed as MacOS X has a BSD interface to the Mach VM. Mach has always had this sort of relationship with BSD and it still exists. 

iOS…
