Surely that just reaffirms everything we know about Nike's morals? Namely that they are more than happy to support doped sports people, in fact there is some evidence they facilitate it.
They don't have morals, they have a legal obligation to maximise shareholder value. She still generates money for them even with the doping conviction.
Nike said she did not dope intentionally and will continue to support her ! Well we all know where their morals are !
