The real risk to MS here is when people take the plunge and see how much nicer a (well supported, well put together) Linux distro is, compared to Windows etc! Will they want to buy their next laptop at home with MSFT installed? Plus, if countries moving off Microsoft put a fraction of the savings into libre office product development, it might get an even more lopsided comparison!
As someone who regularly uses both, and even in spite of the ad avalanche that (a bog-standard home install of) Windows has become: [X] to doubt. I regularly have issues on my corporate Linux laptop that I suspect wouldn't ever happen on Windows. Fleet management is easiest on Windows, with Active Directory, Group Policy, images, etc. Maybe package managers make software management easier on Linux, but fleet sysadmin is basically built-in on Windows.
Linux is superb for servers—I use Proxmox VE as the hypervisor on my homelab—but it still has a rather long way to go as a sharp-edge-free desktop OS, regardless of whether it is for home or corporate use.
