I think it's also the societal stigma of men being raped. It's hard enough for women to come forward. We blame women for rape all the time - "What did you do to invite it? You must have done something, worn something, etc...." - it's even worse for men because they're often seen as NOT masculine if they're assaulted sexually. Couple that with the fact that many of the men involved in this case are very wealthy and powerful.....well, I'm surprised he came forward at all, considering how he was treated when he went to the authorities 10+ years ago.
