Twitter CEO Dick Costolo (@dickc) responds to the disturbing news that the Chinese government sentenced ‘activist’ Cheng Jianping to one year of ‘Re-education Through Labour’ on Monday for “disturbing social order”, after she retweeted a satirical suggestion (from her boyfriend) on October 17 that the Japanese Pavilion at the Shanghai Expo be attacked.

Will it do any good? Probably not. Twitter is banned in China, after all, and everybody knows that governments in communism countries with atrocious human rights records always follow the exact same rules they impose on the people – so they won’t even see it! – but it’s encouraging to witness somebody in Costolo’s position being proactive.

Although if he suddenly disappears, we’ll have a good idea of what might have happened.
