I doubt that true as vacuum packed removes all the air. I have eaten moose meat vacuum packed 4 years earlier and it was just as good as the first year .
I think it was more because being plastic, the vacuum wrap gets holes poked in it from being moved around in the freezer and then you get freezer burn. If no holes,I would assume it is true. A frost free freezer will do more damage than one that isn't.I wrap all mine in freezer paper. Plastic coated on one side. I have meat that is 5-6 years old and there is no problem with it. I do a store it in the freezer in big zip lock bags, about 8 pieces to a bag, but that is more for convenience in moving it around.
