How is Apple able to sell OS X for a profit when it's based off Linux which is open source/free?
Isn't that illegal?
>How is Apple able to sell OS X for a profit when it's based off open source/free software, isn't that illegal?
No, not at all, see: Red Hat Enterprise Linux.
>OS X based off Linux
This is patently false though.
This is also false.
OSX is descended from NeXTSTEP.
NeXTSTEP is at its core was the Darwin 'kernel', some fancy really nice APIs and a Display PostScript windowing system.
Darwin is a Mach microkernel, combined with a bunch of NeXT servers (services in this context, not a physical server, yes I need to explain this to /g/) and the 4.3BSD userspace (inc. all utils)

99% of macfags weren't even born when that happened desu senpai.
Free doesn't mean open source, open source doesn't mean free.
Free as in free speech, not free as in free beer.
OS X is a proprietary operating system, and therefore is not 'free'. Fuck you. fanboy hipster faggots

It would be 100% legal to sell an otherwise proprietary OS with a GPLV3+ kernel, and it always will be because anything else would violate the principles of free software
If you can't use GPLVXX code ~ALONGSIDE~ proprietary software, then you don't have the freedom to use GPLVXX code as you wish
OS X is based off NeXT, and is still the same OS from the 90s because apple is notorious for technological incompetence, if not worse.
Linux is an enterprise hackjob that, nonetheless, is much more useful if you actually want to "compute" using your computer instead of "experience" the results of other people's computation. It's more similar to other "REAL UNIX" systems than OS X in practicality.
Do not confuse the UNIX certification for UNIX usefulness
Darwin is available for free under Apple's license: https://en.wikipedia.org/wiki/Apple_Public_Source_License
There were a few forks of Darwin back in the day, but I think they all died off.
The only proprietary parts are some drivers, and of course Aqua (which is really a separate project)
According to Dennis Ritchie Linux is closer to what he considers Unix than any of the modern Unix flavors.
>Dennis Ritchie, one of the original creators of Unix, expressed his opinion that Unix-like systems such as Linux are de facto Unix systems
