People define "fair" in a really strange way. I read it as "doesn't break my perceptions of what's good and bad." A coin flip is "fair" in the game-theory sense, so even a cube so degenerate that whoever goes first always wins is "fair."
If the cube is built as a pile of "the best cards in a vacuum," mid-range is pretty much the only viable strategy. People include objectively bad cards (ie. Worldspine Wurm) in their cubes just because they're good in the context of another card. For example, Emrakul is nearly worthless without some means of cheating his cost or Channel.
