Translation : "I have no idea what I am saying and am just talking out my a**"
I am guessing you have absolutely no evidence whatsoever on how many people are and are not, abusing Apple's return policy. I can't believe people are for this sort of thing. Basically, Apple is saying they don't trust you. They're telling you that right from the moment they sell you something, they think you are an underhanded scammer who will be abusing their warranty; I can't understand all the "rah rah, go Apple!" talk from some people over this. Personally, I am insulted by it.
Part of the problem are the myriad customers who abuse the system.
I'm sure Apple has had quite enough of bogus claims. Photoshopping receipts (admitted to previously in this thread) falls under this general category. If someone is capable of THAT kind of fraud - to take the time and actually do all of that, then you can imagine how easy it is to misrepresent the facts about user-caused hardware damage when asked about it.
