Is this a purity thing or does it have practical implications?

Every OS will have to when it runs out of resources. No overcommitting means it's less resource-efficient too, so things aren't that simple.

When have OS personalities ever been a commercial success? Every product that built on it went nowhere.

Containers and Flatpaks prove otherwise. Static binaries exist, too.
Also, if you're extending this Linux / Windows comparison to include the userland, then Windows is no match for Linux. Not when Microsoft is actively sabotaging Windows.
> Having access to a ton of file systems is great, but the usage outside of ext4 is going to be comparatively low.
What on earth? There's more use to filesystems than mounting it at root. Are you really claiming that OS personalities are useful, but being able to mount any filesystem is not? That's absurd.
> FUSE is also on Win32 via https://winfsp.dev/rel/
Which doesn't mean much without an ecosystem of programs using WinFsp that's comparable to Linux. Moreover, the long-term development of WinFsp isn't guaranteed, and there remains the risk that Microsoft could introduce changes that might impede the functionality of third-party filesystems.
> It's an uninformed blog post.
Uninformed? While an official Windows-themed Linux distro doesn't make sense, the observation that Windows is declining and Microsoft no longer cares at all what users think is very much correct and obvious to anyone. The fact that Microsoft hasn't ceased development doesn't negate this fact.
