I agree. It was censorship... on an individual scale.
The person who can request a clean copy (and was adamant about it) may very well pass by an offending book on his/her way to a more "friendly" title. Would you rather someone alter your book to fit with his/her sensibilities or not purchase it, period?
But, I firmly believe, most avid readers will read a book that interests them, regardless of sensitive material. We need literature that disquiets, enrages, offends, questions.
The world doesn't come with a button to eliminate unpleasantness, or things that may upset or frighten us. Sometimes, I find myself wishing it did but then, whose version of the world would it be? Would it be the person who finds disabled people leeches or gay people abominations? Would it be the person who thinks the f-word is a punishable offense? Every time we wish the world was different, we wish it to suit OUR needs, wants and ideologies.
Literature helps us navigate the unjust world. Or escape it. Or challenge it. It is up to each person which books are the books for him/her. The extreme abundance of material in existence ensures there is something for everyone, censorship of individual titles not required.
Do you abandon novels if they address certain topics? Do you think Clean Reader was a good or bad idea? Are there books you won't even attempt to read because of their subject matter?
