But they also make is easier to migrate to Windows. .NET Core is a similar play. Microsoft can no longer rely on Windows alone to pull developers and products to Windows so instead they're trying to attract developers to build for any & every platform on Microsoft's stack and support Windows as a by product and maybe choose Azure as well. So in a sense they've switched to a carrot model rather than a stick model.
