His exact quote was, “How exactly did you pay for everything, besides being in a relationship with your coach?”
He basically accused her funding her training costs through her relationship with her coach and questioned how she could have paid for everything besides entering into that relationship as if she couldn’t find ways to fund it the way other Canadian skaters training in Canada have managed to fund their training, despite the high costs of training and living in a Canada, and not all of them are related to somebody.
I’m actually sympathetic to Windsor as he is an Australian skater hoping to represent Korea with his Korean partner while training in Canada, and, thus, would not have had the same funding opportunities as a Canadian would have had, especially Duhamel being a consistent medalist at senior international competitions for years who won two World Championships and two Olympic medals.
I agree that her comment was biting and uncalled for in that why would she question his morality by making it seem like he was duping donors and taking their money and running away with it, unless she was a donor and actually concerned that the money that was earmarked for training would now just go to his personal account. However, I very doubt that was the case because she would have otherwise tried to contact him privately. She did what she did to try to publicly shame him when he’s clearly already down and the center of public scrutiny and added fuel to that fire.
However, that doesn’t excuse what he said, his blatant meaning behind what he said, and why said what he said.
