Giving WINE (originally WINdows Emulator) a cute backronym does not change the definition of the word emulator or whether Wine is one. Please check your favorite dictionaries for that.
> In computing, an emulator is hardware or software that enables one computer system (called the host) to behave like another computer system (called the guest).
https://www.winehq.org/about states that it was an acronym for "Wine Is Not an Emulator", and it isn't now, the opposite of what you claim. (I don't really believe winehq, but I can't find the original discussion on newsgroup archives.)
In fact, it does. Literally, "This is not a pipe," because an image of a pipe is not a pipe.
From the artist:
> The famous pipe. How people reproached me for it! And yet, could you stuff my pipe? No, it's just a representation, is it not? So if I had written on my picture "This is a pipe", I'd have been lying!
