(In this specific case, it’s because Linux has many in-kernel hypervisor systems, not just Microsoft’s. And at no point would they get rid of any of them, even if Microsoft’s is “better” in some sense. That’s not how Linux works: those systems are there to allow various groups to scratch their own itches, not as some central ideologically-driven top-down design. Microsoft can certainly add to Linux—anyone can—but nobody can force Linux to take away alternatives until it becomes dependent in some way on their particular code.)

I'm sorry, but the sentence "every should be afraid of this" is literally Fear.
Yes, Microsoft has a history and yes, we should be cautious. But that's very different than calling for every person to be afraid.
These are all things that Microsoft is either owner or a strong participant. They aren't the same company as they used to be. They don't have one single product (Windows) that everything revolves around. They were losing too much (things like Mobile) to keep that strategy.
