considering how the current regime/dictatorship in Iran is unpopular among the people (at least the majority, they have their own "people" and they are hard to understand) most athletes who just leave the country and say something bad about the regime will get automatically popular. doesn't matter even if they lie or not.
but I can't say the same about her. people really didn't feel sympathy with her, she was OK with everything as long as she was getting paid. and she received prize money probably more than any other athlete in the history of Iran. her medal was historical and she deserved it probably, she was getting paid for her TV interviews (that's a very uncommon thing in Iran) but then all of a sudden when her TKD career was in trouble and the national team coach (who happened to be her childhood coach) said she better think about retirement, Alizadeh found out she is being used and you know the rest of the story.
I still can't wish her bad, she is still just a kid, I think 21. too much happened for her at this young age, Olympic medal, becoming a VERY famous person, marriage, leaving the country, that's too much to handle. she will probably regret some of her decisions when she gets 30.
Beigi ? yeah, you know his coach (who is Iranian too) always claims Beigi lost his semifinal because he was "feeling guilty" after destroying Khodabakhshi in the QF. I believe Beigi probably lost his concentrations after dominating the world champion from his own country. but feeling guilty ? no way he was probably tooo happy
