Huh? My grandma had a Polish last name. It's not new in Germany to have slavic-sounding last names. There were several Germans in the 19th and I think even 18th century with slavic-sounding names.
My mother is German and has a Polish last name as well. A huge part of Poland used to be a part of Germany. In spite of that, growing up in old time Germany, her family was referred to as Polish even though they spoke German and were ethnically German. As recently as 10 years ago, there was a family tragedy and one of the townspeople inquired about the Polish family (specifically referring Polish).
From what my mother told me about growing up, they were given a hard time for being Polish. Most likely that was small town living but that was how it was for her.
To bring it back to skating, you could live for generations in a country, speak the language, go to school and not be considered a native of the country by other natives.
I think it defeats the purpose of the Olympics NOT to have a citizenship restriction. The Olympics are a very special event - not only are people competing for personal glory but in doing so are representatives of their country. The viewers have an opportunity to get a glimpse into different cultures and be exposed to different ethnicities. I was watching the opening ceremonies with friends and we were so fascinated to see how different people look. Each European nation- majority of whom are Caucasian- had athletes that shared distinctive features that were unique to their particular origin.
For me (IMO) the practice of country hopping for competitive purposes cheapens the overall purpose of the Olympics. When I see athletes competing for countries that are not their own and they have no ties to, it brings the Olympics down to the level of any other competition. Why even have athletes represent countries if they are just going to go where it's easiest to qualify?
I know that it makes it difficult to field pairs teams, but instead of easing the citizenship restriction, the ISU needs to get involved with helping countries develop their own pairs/figure skating programs. That is one of the purposes of the ISU is to increase and spread skating. You see what happened to skating in Japan and Korea once they developed bona fide skating stars. Those stars help generate revenue.
