谷歌，為什麼允許澳大利亞過濾搜索引擎

今天澳大利亞的ABC News 和幾家報紙  http://www.smh.com.au/technology/technology-news/google-agrees-to-take-down-racist-site-20100115-maxd.html 都報道了谷歌取消不合法網站的消息。SMH還明確說明澳洲政府同樣有對「非法」網站的規定：

Mr Newhouse believes the site would be filtered under the Federal Government's mandatory filter.
"Sites that promote racial vilification would actually fall within that description [illegal sites] and therefore would be filtered."

請問谷歌，你也要從澳洲撤出嗎？
