Xbox One privacy policies are confirmed

"Today, some gamers choose to sell their old disc-based games back for
cash and credit. We designed Xbox One so game publishers can enable you
to trade in your games at participating retailers."

That is still concerning. It's relieving to know there's no fee, but what if there are publishers that refuse to allow their games to be sold or traded? And if they do allow it, what if they decide to give asinine requirements?
