Amantide, I'm not familiar with the situations you mentioned above. But, assuming they took place as you describe, then I would say no, those situations are not any more okay/acceptable than the Shekhovtseva/Sotnikova hug. I don't think anyone feels that the S/S hug proves anything. I think what people feel is it illustrates there is not enough separation between judges/federations/skaters. That the relationships are too close. Perhaps close enough to change the outcome of the most important event in the sport.
