UNIX is oversold and if it was sold by the same price as other commercial OS back in the day, it wouldn't ever taken over the IT market.

I appreciate the option of running other OS more open to explore the ideas of Xerox PARC.

Also Apple just got UNIX by acquiring NeXT, with Be the music would be other.

Even on NeXT's case, UNIX compatibility, was a means to allow software into the system, not out of the system.

No valuable NeXT application, or for that matter Mac OS/iDevices, made that much use of UNIX APIs.

Still I find interesting that Apple and Microsoft again choose different strategies to try fill the gap between them and FOSS supporters: -Microsoft is gonna include an FOSS unix subsystem -Apple for the first time in his history is going full FOSS for Swift development

It's just the Swift language itself that is open source and a few libraries. Most of the OS X layers above BSD are still closed source.

It's not "more open" than C# and .NET in that regard.

Sorry if I was wrong I absolutely now nothing about c# & .net.

Does it mean one could actually review code and fork theses languages too if need be?
