Believe me, what Yuna's mom told on the paper didn't come off as complaining at all in the Korean newspaper. I don't know why you get the impression like that, but it was as PC as it gets.
Probably some connection with newspaper reporters , which is plausible just by looking at various articles nowadays. But I doubt the company has that much power in anyway, and to do any kind of figure skating business in Korea currently it's all Yuna related. - Super match is exception only because it's Hyundai card show for their card customers, so majority of the people to see the show has free tickets. -
For the legal case, we'll have to wait and see, but I don't think they'll win definitely. They seem to list several possible causes for the sue, but preventing the employees from working in the same business for a certain period is not something that can be easily winnable in the court, because there's conflict with the freedom to choose jobs. By suing the person here, what IB can have is the emotional satisfaction of persecuting this person, but what IB can lose is the company image. IB sports is not like IMG Korea, which was really small that losing face in the society was not such a big deal - and Yuna wasn't superstar like today.- And they have to consider relation with Yuna, if they still wants to do FS business in KR.
All said and done, maybe I'm being too optimistic, but honestly only thing that's on the way of this company is that VP from IB. That's not too bad as the beginning of any company.

And there are tons of good things, one is that this company can focus solely on figure skating development in Korea. She was doing the jr. support even now, but now she can hire more people and the company can find talented skaters and support them to bloom, thus making Korean figure skating scene bloom. Considering this is something Yuna always wanted to do, this sounds like a natural progress of matters.
