THE CANON has bearing only as far as intentions of the authors of creative work mean it to have, which can be "none", and only up until the moment the work is finished, so the "word of god" is piss in the wind as far as judging the intentions of a creative work go
THE CANON is not the creative works, but the hamfisted, imposed attempt to whip many creative works to a unifying coherency (easy with works from the same author, difficult with a property that whores itself out) - THE CANON is not the creative spark spawning those creative works, it's the individuals responsible for the particular creative work - they miss things, they get creative with interpretation, they add things, they recontextualise, they transform it, and in the same way THE CANON tries to impose coherency, they impose THE CANON to tell the stories they want to tell; the work is the work and not the well it drew from
White Wolf has the say on the CANON, but THE CANON has no say on the intentions of the game because THE CANON didn't make it - whatever White Wolf said during the creation process does not matter if it was not heeded, and whatever White Wolf says after has no bearing because creative process is already over with
whatever is in the game is what the story of the game is, and whatever of the THE CANON accords with the individual work is the only CANON that's relevant to the game, end of
you don't get the game's story and literary intentions because there's bug in your brain that does not allow you to and you're post hoc using materials irrelevant to judging the intentions of the game (CANON)
