"I would conclude that a hyperlink, by itself, should never be seen as “publication” of the content to which it refers."
would seem to suggest that merely hosting a torrent file, which is analogous in function to a hyperlink, cannot be seen as equivalent to hosting the material to which it grants access. While one of the judges said something to the effect of "intentions matter", there could be a fairly strong case here.
IANAL, don't go starting a torrent site in Canada on my advice, etc.
