You meant USADA, right?
Table tennis, for example, is basically a bunch of Chinese people battling it out for gold for their host country. Am I supposed to root for the Chinese-Australians as if they're any more representative of me than the Chinese-Canadians?
It's particularly damning that you picked two countries with almost entirely modern colonial populations.
Cf. Rhythmic gymnastics free routine is borderline but there's a whole bunch more set pieces the young women do with balls and hoops which are sport. Figure skating is also borderline but does have figures and set moves and a high physical danger factor (you try leaping high, at speed on the ice, or being lifted). Freestyle skiing doesn't belong in the Olympics.
