That's what I meant with the last paragraph. Linux doesn't come with a licensing cost; maintaining a working "Windows backend" to wine is effort. Just bundling with Linux seems lower effort and cheaper. Cf. also just about all of the system containerization trend and what's driving it - and it's in part API surface between the delivery and the system.
