That’s cool and all, but it doesn’t seem relevant to the point. Metaphors eventually fall apart because no two different things are literally the same.
But the idea that you don’t mess with a classic still stands and by Blizzards own naming scheme they are considering Classic WoW a “classic” here in a sense even if it is a bit of a pun. The actual creators of the original WoW might still be alive, but they are definitely not who currently exists at Blizzard.
