It's completely understandable for those who 'initially won' and was revoked their result. Frankly, people, imagine you yourself won but 2 weeks later you are told it was a mistake, it can be devastating. I am standing in a neutral position and wondered how can this be done better to be FAIR to everyone, it's very difficult. Try and put yourself in the opposite position and THINK for a moment before you react and treat others with your respond.
What comes down to this, I feel, is that it's a difficult situation to begin with. Someone has to be disappointed at the end of the day.. In some way or another, if the US government can make it a happy ending for everyone, that'd be cool. Though pretty unlikely..
And it worries me that people are trying to file lawsuit and all that, than to play to their rules. That can upset them to cancel the lottery altogether because of how people behaved so negatively towards it. Is that what everyone wants?. This is THEIR game to begin with, you are a player. You play by their rules and regulation.
If say, I was the loser, the initial 22k people won and they proceed with the others being drawn, I would assume this is how they wanted to run things and I can't do much. Just have to accept it and try my luck next year again and again.
I know so many others coming from countries that are not even eligible to take part, and have invested a lot to get to USA, they have worked so hard and have a hard time trying. They are bitter at this lottery's existence because they aren't given the fair chance to try out too, and have to work extra harder and have no 'luck' to depend on. Consider all of you very lucky already that you are even given the chance to take part in this, don't take this opportunity for granted by lashing out none stop.
We all could be losers at the end of the day if people keep making this difficult to them...
