"Google strikes a blow to China's Great Firewall." This gushing headline, from the Guardian, sums up recent press coverage of the internet search giant.
Google created a specific portal for China-based users in 2006, Google.cn, which complied with the country's censorship laws. So, for example, searching for "Tiananmen Square" via Google.cn would retrieve pretty photos of the square as it stands today, with the 1989 massacre stricken from the record.
But following a hack of Google's mail service, Gmail, apparently from somewhere in China, Google decided to stop playing ball, relaxing this censorship. Over the next few hours, thousands of search queries originating from China featured the query "Tiananmen Square 1989".
