The only new thing that Ubisoft have here is making the database of all transactions public. These hardly count as real NFTs. You can only transact them on Ubisoft approved market places, only centrally registered Ubisoft accounts can hold them. And since they control the game, they have all the rights to ban items from the game, even if they insist they can't reverse transactions.
