This isn&#x27;t about the triviality of implementing rc4, it&#x27;s about the absurdity of banning information in a general sense.<p>Information can be copied at zero cost, transmitted instantly over vast distances, and stored permanently and undetectably in the human brain. Information spreads like a virus in a very literal sense - you overhear a scrap of plot and suddenly a whole film is spoiled. Trying to ban information is a futile as trying to arrest people for catching influenza. This isn&#x27;t like banning campfires, or even like banning firemaking implements, it&#x27;s like banning the very idea of fire.
