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?
Firstly, it's not based on Linux. It's closer to BSD, but has bits and pieces from everywhere.
Secondly, they don't sell it (at least not any more), it's a free download (although they do still officially say you're only allowed to use it on their computers.
Thirdly, for all the open source stuff they use, they do release their source. http://www.apple.com/opensource/
When do you dump shits learn for once that OS X is NOT based on Linux or GNU userland tools.
It is based on Next/OpenSTEP UNIX with a LOT OF APPLE PROPRIETARY CODE and some Mach research kernel shit and (Free)BSD userland tools thrown together in a big pile of shit.
They can use the stolen/copied BSD stuff and earn money with it because BSD license allows it.
Even Sony does it with the PS4 (Orbis OS is based on FreeBSD9).
How is Samsung able to sell touchwizz for a profit when it's based off AOSP which is open source/free?
it's a variant of Unix, and even if it were based on GNU/Linux, you could sell it for money, the only problem would be that you would have to provide source code and build instructions to anybody that owns a copy of the OS, and anybody would be allowed to redistribute it
