I'm pretty sure the ad is real, it's just the context is interesting. If it was really placed in Atari User (as this article says) then the "Well, stop dreaming" jibe is most likely aimed at Falcon. If it's from some other mag not sure what sense would it make though...
EDIT: I see @arcanist nailed it with the true meaning
