You do now. Every book store decides what they are going to sell. We just didn't know about it before. The beauty is that any author can now simply take their books off iBooks and sell it in an open epub format and skip the distributor.
Regardless, this is a bullshit move from Apple, and it's starting to wear on me. And that's saying something, because I do love their products and forgive many missteps because I really do love their products.

I am in this case amazed to find a book store refusing to stock a book on professional writing because the book contains details of other book stores that a writer might find useful, or for them to suggest to the author that those elements be removed from the book as a condition of sale.
The comparison is absurd anyway as the main drive for the selection process of what to stock in a brick and mortar bookshop is the limits of physical space in a bookshop, which is not really an issue for ebook stores.
B&N is stocking Amazon published books on their website according to the first article you linked, just not their physical books in the physical stores. And they are doing a blanket restriction, not picking through the contents of the books and demanding editorial control.
