said by fatness:It's strictly business, nothing else. Armstrong has been retired for over five years. He will now no longer compete in even triathletes as before. So he is done as competitor and as a dominant active athletic name. Now that isn't competing all and out of the sport for such a time all that is in the news is the doping. Nothing else. In only makes sense to drop him by most sponsors.
Anheuser-Busch, Trek bicycles, Radio Shack, Giro (helmet manufacturers) and Honey Stinger also dropped him. He resigned from the FRS Co board.
I don't think Nike ever dropped Tiger Woods, did they? They dropped Vick but re-signed him when he got out of prison and had shaped up. And they removed Paterno's name from their child care center.
