Many things I've read over the last few years about Microsoft is that it's utterly disfunctional. It's become so big that it's impossible to achieve any kind of coherence. As another comment pointed out: they've had 10 years to make the UI all look the same and still haven't achieved it! A single dev could have redesigned the whole thing in a couple of years at most so it can't be a technical issue: it points to them either having incompetent management or just being too damn big to actually manage!
Now I've worked mainly for large corporates over the years and they're never a single entity: they're always made up of multiple internal entities whether officially or unofficially. And they all have their own goals so steering a company as a whole is not an easy task but Microsoft are a fucking mess and thanks to all this forced shit, Windows 10 will be the final version of Windows for me.
So what does that mean? It means that Linux has 4 years to get its act together before I switch to it permanently, come hell or high water. Coz right now, Linux is not a replacement for Windows for a great many people. Myself included. Even though I've tried multiple times with Fedora, Pop_OS and Ubuntu, shit always goes wrong. Always: dodgy sound issues, Nvidia drivers issues, scaling issues etc... stuff I don't get with Windows! Ever.
