Saying it's wrong definitely isn't a fact, I'm sure the gfx team that made the original g2k2 heads don't think it was wrong, maybe you didn't learn what I learned in school many years ago, the difference between fact and opinion.
Let me use dictionary.com real quick.
fact=Something demonstrated to exist or known to have existed
opinion=A judgment or estimation of the merit of a person or thing
Now, here's the information, you can agree with real information, or you can continue to argue, your choice, but eventually I will stop arguing.
I believe your opinion that the shading is wrong is only an opinion and not a fact because there is no exact measurement to if shading is wrong.
Also, I believe it to be an opinion because in my opinion fixing the shading will do no real good, I belive the current shading to be fine. The gfx staff chose the shading they liked, and they stuck with it, I have no reason to fix it. Even if it is "wrong", I don't care, fixing the shading probably won't make a difference anyway.
Facts, I can take into consideration and actually do something with.
Opinions can be taken into consideration if the opinion is a good one.
It's also better when you can get people to agree with you that the shading is wrong.
If let's say one or two more people complain about the shading, then it might make me think I should fix it, but the opinion of one person doesn't make any difference in my mind, when obviously the opinions of many of the people that supported g2k2 didn't think the shading was wrong.
