Its not the central issue here, but the statement that only a fool would cut a cable down is nonsense. There's absolutely no reason that a 'cut down' cable wouldn't perform just as well as the original size. Its not difficult to find cable manufacturers that are willing to support their product by modifying length, type of termination, and performing repairs, regardless of who the original owner was.
Also, how does the fact that counterfeit cables exist constitute a valid reason for refusing to modify authentic cables?
