The first sale doctrine would beg to differ with you. Once I buy a work I'm free to do whatever I'd like with it, provided that I don't infringe on the copyright by making more copies. I absolutely can remove whatever I would like from it. Copyright protects publishers from unauthorized reproductions. AT&T are making an unauthorized reproduction when they insert extra things into something that isn't theirs.
