The free software Tor, popular among Iranians, promises anonymity by “redirecting encrypted traffic through multiple relays . . . around the world,” making it difficult for a regime to intercept a transmission.26 But if it effectively monopolizes the provision of Internet service, a desperate regime such as Burma’s in 2007 can always respond by shutting down the country’s Internet service or, as Iran’s government did, by slowing service to a paralyzing crawl while au- thorities searched electronic-data traffic for protest-related content.27 Even in liberal democracies, issues of access arise. Recently netizens worldwide—and the U.S. government—have become concerned over ex- cessively broad legislative proposals in Australia that would force Inter- net service providers to blacklist a large number of sites for legal and moral considerations (including the protection of children).
