Dustin Kirkland on his blog:
Finally, I imagine some of you — long time Windows and Ubuntu users alike — are still wondering, perhaps, "Why?!?" Having dedicated most of the past two decades of my career to free and open source software, this is an almost surreal endorsement by Microsoft on the importance of open source to developers. Indeed, what a fantastic opportunity to bridge the world of free and open source technology directly into any Windows 10 desktop on the planet. And what a wonderful vector into learning and using more Ubuntu and Linux in public clouds like Azure.
Fascinating times.
