That's the thing, everyone involved should feel reponsible.
Teenage girls can develop eating disorders without any outside influences, so if it is really true, that some people in her close environment were controlling her food intake ... well that would be indeed horrible.
And there's one thing I want to mention: The look of some pairs is very strange ... you see a bulky large male throwing and lifting around a ... child. And I guess the new scoring system influenced that a lot, I mean ... they were doing triple twists two decades ago, but they were smaller. Now the guy has to bring his arms down to shoulder level to get the level and the throw must be really high to get good GOE as well and it only can be really high if the girl is tiny. I don't like it.
It's not that simple. For example look at team Mozet: Volosozhar, Stolbova and Tarasova looks absolutely normal, all these pairs has high twist and throws. Or the opposite - Kawaguti is tiny but their thows aren't big and they has problem with twist. So for me it looks like some coaches know how to learn these elements wothiut making a skeleton from a girl and some coaches don't know this and make girls to lose weight more and more.
