Would you use OSX over Linux if Apple decided to open-source OSX software line to the world?
This incl. all the closed source kernel extension, bootloader, and etc. (excl. all Apple services - iMessage, Facetime, App Store, iCloud, iTune). And we can make it hardware friendly as of how Linux handles it, and we can do whatever we want to make OSX better.
Direct instinct, please. Do not complicate the poll. (forget about conspiracy theory, politics, whatever).
Would you pick OSX if it is open-sourced?
However, having said that, OSX is not that bad after all, IMHO. There is good thing about OSX, and as has said, it suits for certain needs and tools.
Just pick whatever OS that works for you, I think that's the most important thing.
