I'm a very big supporter of the check down and have the biggest number of hands go against an all in. In this situtation, the check down as not the correct play. You were a long way from the money (30+ is a long way) and stack size is more important right now. I can also see why people were whining about the lack of a check down.

Many people are learning the concept of checking down to eliminate a player, but the bounty tournaments change that idea quiet a bit. It's now worth something to be the one to take a player out, instead of it getting you 1 step closer to the money. Had this game been a standard game (no bounty) I can understand their complaining, but because the bounty is generally 1/5 to 1/6 of the buy-in it becomes ideal to take people out. After 5 or 6 KO's you are freerolling, usually with a sizeable stack.
