The thing is China has a pretty funny idea of what constitutes "sensitive". Such as free speech and human rights.

is this related GPS? But ask yourself first, does it make sense ? do you know the entire story but just Plagiarized from you media?

When the Chinese government is frivolous with blocking access to websites and services, it's not a huge leap to worry they may be frivolous in denying access to other services they provide. Anniversary of the Tiananmen Square massacre? Maybe we'll bump down the resolution in that area to make protests more difficult.

Not saying they're going to do it, but just the smallest uncertainty means you'd rather trust one of the 3 other competitors in the area.

edit: I wonder if putting keywords on this page will get them denied access to these comments 六四事件 天安門廣場抗議 天安門事件

Haha, it looks like putting in those words maybe did block the Chinese.

Nothing frightens me more than a society with no freedom of speech, except for one that gleefully has none.
