China: Not Worried About Twitter’s Decision to Self-Censor · Global Voices
John Kennedy

Twitter's announcement Thursday that the site will begin censoring content according to the relevant laws, regulations and policies of each country in which it has users, was followed not only by American netizens, but discussed as far away as China.
Although Twitter remains blocked in China, the site's Chinese-language users, an assorted bunch, moved quickly to source people to translate [zh] the company's statement and figure out what it might mean—a Twitter.cn, for example, or, as Ai Weiwei wonders, if the time has come to move on in search of a new platform with more respect for its users [zh].
Wen Yunchao, a well-known Internet activist from Guangzhou now working in a sort of domestic exile in Hong Kong as a producer for a new TV station, posted his thoughts on Twitter's new censorship measures to his Twitter account (@wenyunchao) several hours ago:

从推特发布的公告来看，现在是比以前进步了，以前是接到一国政府要求删除推特信息时，全球均不可见，现在是只是该国用户不可见。（1）
推特新的审查政策不会对现有中文用户产生影响。现在翻墙使用推特的用户，推特很难从技术上认定这些用户来自中国，因此亦无足够的依据屏蔽这些信息在中国的显示（无从显示）。（2）
推特想进入中国，至少存在两在不可克服的障碍。一是黑箱的审查机制与透明规则之间的冲突无法解决。除非像谷歌那样以内资公司的方式存在，否则推特屏蔽特定信息将面临用户的诉讼。（3）
二是推特既然有新浪的政府公关能力，亦无法做到像新浪一样巨量的审查投入。对于中国当局来说，不会允许一个比新浪更宽松的类推特平台在中国提供服务。（4）
