Don't they have a sticker on the cellophane wrap on the package with some sort of legal agreement stuff on it? They should definitely put it on there.
They might be doing this to keep people from buying, copying, and selling... which makes sense to do, actually, given the price of the products.
It doesn't surprise me that Centerpointe, being as unabashedly money-driven as they are, would do this. If you prevent people from selling their CDs, then customers must use Centerpointe as the sole provider of the product, so ... more money for them.
