Imagine you really enjoyed your meal at a restaurant, and in the end the waiter tells you it's made of people. Is it still a good meal, and most importantly, would you recommend it to other people?
I really don't think this is the same thing. A closer analogy would be you enjoy your meal at a restaurant, and at the end the waiter tells you the chef was a robot. Why should the provenance of something make any difference at all? If the author of your favorite book was convicted of some terrible crime, would the book you loved so much before you heard the news suddenly lose all its value to you?
