A bookshelf is a problematic comparison since we do have devices that people buy that has a built in bookshelf, one that can remove books at the company discretion. The digital books you loaded it up with at home is not owned by you, nor do you have any natural right to the book or the bookshelf. However, they won't lock it up and demand payment. They simply just lock it up at the discretion of the company. The digital bookshelf will record and analyze what you read which is a bit of switch-and-bait tactic.
