I don't know if this is 100% true, but if true it looks very reasonable to me. It paints quite a different picture than what it's been, for the most part, assumed in this thread and other forums. For instance, Nvidia wouldn't be forcing anything. I do understand, that maybe before now they'd get the warranty from Nvidia no matter what, but personally I see no reason for Nvidia offering a warranty if their specs are not met. From manufacturer's perspective not getting the warranty might be scary enough that it really forces them to the only option, but it's not like Nvidia is aiming a gun to their heads.
I think that when Jacob Freeman said "It was removed in order to 100% comply with NVIDIA guidelines for selling GeForce GTX products" he might actually be like saying "If we want to get the warranty...".
