Follow the money
Microsoft has been always about the money... not about the high “moral” ground.
Microsoft used their dominance to maintain their dominance. These days Apps are money, Linux/Android are where the Apps are at. If Microsoft didn’t find a way to recover from their crappy store and mobile efforts it could threaten their entire business. The ability to run Linux on Windows is huge. It was something that needed to happen anyways to support Linux instances in the cloud (Azure).
Satya Nadella is a smart guy. Why bitch and complain about something that can bring in $$$$.
He’s doing the same thing with IE/Edge. Why spend the money to fix crap when you can bring in a open source browser that are cheaper (to support) and better.
Windows 10 needs a lot (ok a shit-ton) of work, but Microsoft doing amazingly well elsewhere.
My biggest complaint with Microsoft’s lately is the data slurp...
