Not sure why you got a letter from KZ on your Keystone window, but anyway.... As a parent, how many times did you tell your kids not to do something if you thought they might screw it up? The window has a screen on it for a reason, to keep bugs out when it's being used for ventilation..... The big issue is to make sure the red handled emergency lever is locked and secured before travel. Most of us use either a bungee cord or a "big rubber band" and "sort of" ignore the "don't use this window" from "mom" LOL
