And this is exactly because of this mentality that windows next move is to add a Unix subsystem (Ubuntu) aside all the old crap instead of just being Unix compliant and progressively drop old chunks of code as year goes by like Apple started to do 15 years ago.
Still I find interesting that Apple and Microsoft again choose different strategies to try fill the gap between them and FOSS supporters:
-Microsoft is gonna include an FOSS unix subsystem
-Apple for the first time in his history is going full FOSS for Swift development
