This isn't breaking news - it's been known and understood for more than twenty years.
Microsoft could end the misery tomorrow. They know it.
All they need to do - they know it - is sandbox their lacklustre OS inside a Unix. That's all. Any one of them. A Linux. A FreeBSD (like Apple's). Like the bulletproof OpenBSD. And they know it.
But they continue to push this bluff, a scam that costs people so much. And it's not hard to figure out why. It's all about the Giga-Benjamins. Change the internal architecture and they lose their ISV base, which is everything. Sandbox their Windows, and ISVs will simply bypass the Windows API and deal with the sandbox directly. And then Microsoft will be completely out of the game. Relegated to making Zunes. (You gotta admit: the product may have been crap, but the name was a winner.)
If you're not on Windows: stay where you are. Stay on Apple's macOS. Or a Linux. Like Mint. Or OpenBSD. Don't move. And, for goodness sake, don't start seeing Microsoft as some sort of benefactor. Because they're not. They're the Main Offender.
