I think I should have emphasized that this was just me non-native speakers gut reaction. Maybe a competition is more what I meant? I think about competitions in school where you had no choice but to take part (e.g. maths or reading or sports), or the competition from the movie Hunger Games. Somehow a prize sounds more like something I get for a bonus, while competing against others is to me more associated with “There is not enough for everyone, this is zero-sum, who is this evil person that would make charities compete against each other for their financial survival?”.
