This exposes again the huge difference between Microsoft and Apple.
Microsoft will invest heavily in integration while Apple circles the wagons in propriety. In the few cases when Apple opens up it is late and smallball.
This is just Microsoft trying to hijack POSIX. Interesting, but useless to the larger MacOS/UNIX/Linux community that already has all the tools.
Microsoft is desperately trying to become significant in the OS space again.
The first thing I do with Windows laptop is install Cygwin.
I can hardly remember how to navigate the convoluted Microsoft OSs, and spend all my time on MacOS or ABW (Anything But Windows).
You don't have a clue what you are talking about. Apple has been publishing Open Source software for years. For example: CUPS, the printing system used for both OS X and Linux, WEBKIT, which is used for many web browsers. Both open source, both owned by Apple. HealthKit, open source. Apple owned. Bonjour, Open Source, Apple developed, Apple owned.
Open at the source. Open Source software is at the heart of Apple platforms and developer tools, and Apple continues to both lead and make significant contributions to many Open Source projects. Major components of Mac OS X, including the UNIX core, are made available under Apple’s Open Source license, allowing developers and students to view source code, learn from it and submit suggestions and modifications. In addition, Apple uses software created by the Open Source community, such as the HTML rendering engine for Safari, and returns its enhancements to the community.Apple believes that using Open Source methodology makes Mac OS X a more robust, secure operating system, as its core components have been subjected to the crucible of peer review for decades. Any problems found with this software can be immediately identified and fixed by Apple and the Open Source community.
