The idea that Ghomeshi was “credibly accused” is rather the point. In the only cases that went to court, he was found not guilty, and the judge went on quite a tangent about how the witnesses had lied to and hid evidence from the court.
If that’s not enough to clear his name, how can anyone ever escape the stain of a credible accusation? It seems prudent given that problem to ensure that no accusation will be credible.
