He claims this is done to confuse radar systems, to give protection to military aircraft. It may well be, but what are the consequences of dumping this into the atmosphere, it doesn't just float up there despite being very light, it eventually will come down with rain or just the action of wind and gravity. Then we could breathe it, drink it, and/or it could ruin our soil for crops. Sure it may be used as an anti-radar tool, but it could still hurt us.
