But you weren't playing a smart big stack. If you effectively sit out, playing only your best hands, assuming you don't get any big hands in the short time of the bubble, big stack continues to take yours and the other mid-stack's blinds, meanwhile the disconnected player stays the same, as he loses his SB but gets it back when the OP folds to him. How can you finish 2nd if one player is gaining, one is staying the same, and you're losing chips?
As to whether it's ethical, the goal of the game is to maximize expectancy for you. If you are doing anything else, like soft playing, chip dumping, etc. it's unethical and illegal. This play though is smart tournament strategy and completely ethical and within the rules.
