Moreover, it's increasingly easy each year for companies to support BYOD and let employees procure whatever they want that meets IT requirements. My current employer gave all non-tech staff $2000 to buy themselves a laptop, which was then enrolled in some fleet management systems with almost a single click.

Frankly, I see very few people choosing Windows anymore.

Also, another point to add: Microsoft's Intune fleet management system is perfectly capable of managing Macs, and you can use AD as your IDM source of truth for just about anything, including SSO for Google Workspace & ChromeOS devices.

To your last point, Windows Server is a hard requirement in many enterprises because of legacy or procured software that requires it. That is entirely separate from end user computing.

(I used to run end user computing for an F500, and I also ran the Enterprise Apps org at the same time. This was from about 2008-2015, and initiatives including mass migrations aware from MS Office to Workspace, and replacing thousands of Windows laptops with Chromebooks.)
