Especially when it’s becoming increasingly obvious that Windows isn’t the future. Windows has maintained dominance because it is great at backwards compatibility. ARM erodes that advantage because of architectural differences, coupled with the difficulty and drawbacks of emulating x86 on ARM. Mobile is eating more and more market share, and devs aren’t making enterprise software for Windows like they use to.
No one working on a greenfield project says “let’s develop our systems on Windows server” unless they already were doing that. Windows as a service is the more likely future, funneled by Azure.

Even some shops working with Windows Server are asking "wait, why are we paying for these licenses?"
Then it comes down to whether it's cheaper to rewrite legacy applications or continue to pay for licenses.
My former employer made this decision recently. They moved off .NET and onto a web app with a RHEL server. Time will tell if they pull it off.
