it's also fascinating how you could enjoy something if you didn't know how it was produced, and then the act of knowing would remove the enjoyment you were deriving from it.
Would you feel differently about, say a book you read and somewhat enjoyed if you later learned it was written by a fascist? It sure would make a difference to me. Have you never consumed any sort of media that you later felt was tainted by who created it, or used a product that you later decided not to use again after learning how it was produced? There's even a colloquialism referring to this very thing, about "knowing how the sausage is made."
