Collateral freedom

From Wikipedia, the free encyclopedia

Collateral freedom is an anti-censorship strategy that attempts to make it economically prohibitive for censors to block content on the Internet.[1][2][3] This is achieved by hosting content on cloud services that are considered by censors to be "too important to block," and then using encryption to prevent censors from identifying requests for censored information that is hosted among other content, forcing censors to either allow access to the censored information or take down entire services.[4][5][6][7][8][9]
