This is the same logic people use to block modification of movies, music, books, video games, etc.
"The artist wants you to experience their art a specific way and the ability to [censor profanity/add zombies/change the ending/remix it] wrests control from the creator and allows people experience their art in a way they didn't intend, which is bad"
Curiously though, these people never mention altering food as destroying the experience the chef wanted them to have. For some reason consumers are allowed to have food preferences that modify art, but not preferences that modify other types of art.
