You have to pay me to use Windows and macOS. After speeding years using both products, I don't want to use them any more unless I'm getting paid. I personally do not need any software that is tied to either platform. Professional, depends on what needs to be done.
Not all have this view and nor most will.
Hard-core gamer will most likely keeping on Windows unless developers and distributors change their ways.
Some people buy a computer because of the OS it is running and they need select applications to run. Most only need a web browser and it does not matter what OS they run, often it is the least expensive laptop. Something that has a bigger screen than a smart-phone.
Windows backwards capability is also limited. Gaming: never was able to get Slave Zero running on a Windows XP box, only Win98. Development: had to ignore the input event system Microsoft designed for WinForms and WPF, using Win32 message pump directly, because of faulty drivers and new features breaking backward capability.
