The Jaron Lanier quote may belong in a criticism or media references section but the fact that he has made an unsubstantiated assertion in a book critical of the articles subject doesnt go far to proving that this is any sort of motto If this was a citation to a place where members of the movement whose motto this purported to be were making this assertion thatd be a better citation If you found a PETA brochure that stated Killing animals is fun is the unofficial motto of the meatpacking industry itd be about as credible as Laniers quote
