    So I say: Emacs is the best advertising medium, the best promotion of
    the idea of Free Software.  So, in my point of view there is value in
    itself if it runs smoothly on non-free operating systems like MS
    Windows or MacOS. It is, so to speak, a foot in the door.

All else being equal, it is useful that Emacs runs on these systems.
But that's not the issue at hand.  The issue at hand is whether to
design Emacs features to work better in the context of the GNU system
or to design them to work better in the context of Windows, in cases
where those two goals conflict.
