In this case we cannot say that the athlete does not like her country or her nationality because until these war-related sanctions she always used the name of her country in addition to the fact that almost certainly the costs of going to the World Cup are borne by Russia therefore, it seems to me that the question that Russia never cared about its people do not apply here.

As far as I know, people who never identified with the regime ended up leaving the country, asking for refuge in other countries or even ending up having the nationality of that country and forgetting their Russian nationality.
