Why so many saying it's not cheating? They were not taking it easy, which would be understandable, they were trying to lose!
Cheats got what they deserved.
I fail to see the cheating at all. Personally I disagree with it, people harp on about football and styles, how you play but ultimately football and all other sport is entertainment, if its not entertaining it shouldn't be on. Those players turned up to compete in front of paying customers and didn't provide what those people paid for.
If you go to the cinema and buy a ticket for whatever film, and it stops working 15 minutes in I want my money back. They paid for something and didn't get it.
As for cheating, its okay to play to win, but its not okay to play to lose, that makes no logical sense, losing is not cheating. There is a game and there is always a loser(okay most of the time), has every person/team that has lost before been cheating? Cheating isn't a good argument, they broke none of the rules as laid out, they weren't doping, they weren't using non regulation equipment nor did they shoot the other team.
As I said, I disagree with it, they failed to live up to the moral responsibility placed upon them by agreeing to compete in the competition, to provide the entertainment of a badmington match to those who were paying to see it.
Sport is entertainment, people PAY to be entertained by sport, if you don't entertain, people won't pay, your job is gone. They let their teams(as in team china/whatever) down, and their fans, and the customers.
The sport let them down also, they shouldn't have to compete in a format that puts you in a situation where you can get effect which game you get next by not winning your next game.
I'm not a fan of mini leagues moving into knockout stages, it will almost always encourage this type of thing and we've seen it in football for donkeys years. As always its the money men trying to get the big names into the final to milk more cash from sponsorships. If you do a mini league then knockout round, randomise the draw so no one can know who they will play and try to effect that by changing results.
