This one is fairly simple to work out, if you struggled to get 3 or 4 kills and then got shot down after a hard fight, and bailed wouldn't you want to be able to land your chute safely? It's a Golden rule issue, treat your fellow pilots in the manner that you would wish to be treated. Also, the angry whines that result are never worth it and make everyone else's life miserable.
BTW - I can almost stomach it when the guy who flew my tail off and shot me to pieces shoots down my chute. What is a little more irritating though is when after a good fight some dweeb who wasnt even near us comes over to use my chute as target practice.

PS: And yes, as the WORST pilot in AH, I do have a vested interest in this. ;-)
