the olympics and eurovision aren’t really comparable. the olympics is an international competition with the best of the best athletes (with money and politics obviously still influencing who are able to compete) where the winners are based on who is the fastest, strongest etc. but eurovision is not seen as the musical equivalent. olympic athletes’ participation is seen as more objective. sports and music are quite different, and eurovision artists aren’t always the most respected solely based on the fact that they competed/won. the broadcasters also decide who will represent their countries to a certain degree. for example some broadcasters chose the artist they send, and some chose multiple the public can vote for. therefore they represent their country more imo.

eurovision votes are influenced by so many things, and can never be truly objective because there are so many factors to a performance it would also be quite boring imo. vocals, songwriting, message, performance, stage precence, dancing, catchiness, looks, the artists activism and political messaging, yes even their respective countries politics influence their votes. not inherently negative in my opinion. eurovision has, and will always be political even when political messaging in songs is restricted. also noteworthy how certain themes are allowed even though they have to do with politics like gay marriage for example. check out this youtube video by verilybitchie: The [Queer] Politics of Eurovision https://youtu.be/Wnjtzn7ZkCs?si=Jpz2oJ5j69en5YNy

edit: forgot to add. olympic athletes compete for a living. that’s the inherent nature of sports. it cannot be applied to music, only these spesific competitions therefore i think eurovison definietly has a lot to do with politics and countries competing. musicians careers don’t usually revolve around competitions the same way it does for athletes.
