That boat sailed long ago. Windows has a pretty decent linux subsystem now. Even devs that were hardcore linux enthusiasts moved to windows.
The benefit of linux is that it doesn't force stuff on you that you can't disable compared to windows. If you take that away, there are very little reasons for any normal user to move.
Windows Server won’t be getting “sold off.” I’m not sure you understand just how entrenched Windows Server is in the Enterprise and just about every Fortune 500 company out there, including huge telecoms and ISPs. MS still makes a ton of money off Server, and most of the companies/Enterprise using Server aren’t even thinking about Azure.
I think dual booting is still the way. Gets the best out of linux and eliminates headaches. Boot up times are so fast these days, in and out of the OSs almost as fast as logging in and out.
