it is also very inaccurate to begin with. No software is 'deleted', they added a commandline option for users of the blob, to make things even more convenient for us. ~ and just so you know, i have nvidia installed, but could kill X, unload nvidia then load Nouveau and start X again (no reboot). So i don't see where you get that idea to begin with.
you need to grow up, or at least be a little more honest with yourself.
