Yes, I still do dislike the fact that Diamantidis retired at 30. It is unacceptable and always will be. He will be remembered in Greece as the player who retired at 30.
I can imagine a player deciding to skip one tournament at 30. But not retiring. He did a lot for the Greek team, which is appreciated. But deep inside something is lacking. Still, he was 30 and there was a tournament every summer. Next year there is no tournament and Antetokoumpo is only 22. I know he is becoming a superstar, but that's no excuse. No one is above of the national team. The ones who are saying that Giannis did not loose support in Greece are delusional. Everyone I talked to thinks otherwise.
