Well, basically she is telling them that they are not doing a good job, so it is normal that they are so furious just like her. I don´t have problem with she complaining, except that I am not agree with her, but it is totally expected that she won´t get any favours saying that, and I did not see her complaining when judges gave her higher PCS to her than to Mao.
No I don't think it's extremely deserved but I do like this and I wish more skaters (ESPECIALLY Mao!!!!) did this...but then again Mao never would do that.
