The question isn't asking whether you, a Windows user who runs Windows, benefit. The question is asking what it does to Linux users who don't run Windows even a little. (And I think you know that.)
That's like asking whether Linux users who don't run ESXi benefit from their paravirtualized drivers being upstreamed. No, they don't, but they were accepted with way less bruhaha. And that's despite VMWare blatantly violating the GPL for more than a decade.
