I don't make games so probably not using Unity. I also don't think gnome software like glib and cairo is the "foundation" of the OS I use like macOS. Are you sure you're not a Miguel de Icaza alt account?
Following this thread to this comment has been one of the biggest disappointments of my week. Your paranoid pedantry is not helpful.
What are you trying to gain by this line of debate? That you don't use software made by Miguel?
Okay cool, congrats.
