Wine is a great thing on Linux too…
Wine -> Running Windows programs on Linux
WSL -> Running Linux VM inside of Windows
Wine is more like emulating Windows API behavior on Linux, while WSL is Microsoft throwing their hands in the air and saying "Lets just VM Linux wholesale".
Both aim to avoid Windows, neither replace Linux but instead tries to move more to Linux.
Yet again, because it helps avoid windows.
