I think it is more about money and business.
Mao is the poster child / cover lady of Japanese figure skating since young, with unique selling points including the 3A which are easy sell to catch the imagination of the public. There are a lot of people financially benefit from her stay at the top and have put in the time, resource, and investment from her sponsors, her agents, federations for almost a decade, and they will do their all to ensure she remain at the top or and have maximum chance of success include favourable PR. When you have one sport agency IMG that hold monopoly over the entire industry, 90% who's whos in figure skating in Japan (and the US). They are powerful to control the media output in which they can use to favour to their own most prized asset, driven by business upon the commercial value of the skater.
