On purely abstract basis I suppose what he does is not immoral. On practical basis however there is a certain little voice which says but books are for reading, but what of the mystery of that book left there which someone all the sudden stumbles upon and changes his life.
The people on amazon have already found out about these books. They will probably get them somehow at some point in some way. If however there was a perfect market, or even significantly perfected more than it currently is, that novelty of stumbling upon a book might be completely lost.
I am not entirely certain though. I suppose in one way it is not immoral, but in another way you just get the feeling that what he does is not exactly as uncontroversial as what a doctor does or even marketer.
