I wonder how much of the software you're proposing Apple get paid 99.9% for is open source? (Including the xkcd-famous "one guy in Nebraska" who's been doing his thing for over 20 years)?

How much do all the contributors of these projects get paid?

https://opensource.apple.com/projects/

And all the stuff not listed there too, like OpenSSH, curl, all those little things that pretty much _every_ OS uses?

And the predecessors? BSD, Mach, FreeBSD...
