Twitter Caves To International Censorship Laws. Twitter CEO: We Are Not Censoring the Web. Twitter CEO Dick Costolo took the stage at AllThingsD‘s media conference in Laguna Nigel, CA, Monday evening to defend the company’s new censorship policies. Twitter announced last week that it would begin censoring tweets in certain countries to comply with local laws. The move sparked outrage among many users, who gathered under the hashtag #TwitterBlackout and pledged to boycott the service on January 28. But as Costolo argued on stage — and my colleague Josh Catone pointed out last week — Twitter’s new policies allow for greater freedom of speech on the platform.
