ATT Bashing Commerical

Can you tell me why Cox has to put an ATT Help Desk Commercial on where the ATT clerk whispers to the ATT customer to go to COX.  This to me shows that Cox has NO INTEGRITY and the only way they can make themselves look better is by bashing the competition.  If Cox has such a good product, than they should be able to stand on their own merit.  Maybe Cox should re-think who they are using for an Ad Agency.  This commercial makes me want to pull what I have left with Cox and move over to ATT.  Just sayin!!!!.
