Rather than lend credibility to the 'newsworthy' angle, I suspect their (definitely being behind the leak) motivation is more character assassination.  Seeking to take the wind out of the sails of the defense that is riding very high on public support.  There is almost no one pre-leak who is even agreeing with the moral-degeneracy argument that this big teddy-bear we all love is somehow a sick sex-maniac so we should stop loving him.  So they break out the "ALSO a casual racist when it comes to jokes about his daughter" hand.  This is a clear attempt to demotivate Hulk supporters, and it may have middling success.  But they've basically set themselves up for a default judgement and possibly even treble damages thanks to the sliminess of the action.  The judge, if presented with evidence of this action, is going to throw several books at them, I predict.
