I don't have a problem with "cheating" in the sense you described it, but I want to know if I'm playing against people who are using it, and I appreciate the option to not play with those folks. When I sit down to TF2, I'm not looking to compete with the best reverse engineers, or the folks who throw the most money at their games (in the case of Valve mentioning buying hacks) - in fact, I'm not looking to compete at all. I just want to relax and have fun playing the game, and I can't if I'm being hacked to death.
