I notice Google is not only censoring content to China, but also
content on GoogleEarth.

The Sultan of Brunei's London home used to be noticeable for being
covered by a low resolution image. Now even that has gone and his home is covered by a black box.

Take a look, if you have Google Earth, the following are the Lat/Lon co-ordinates: 51.498097,-0.342308

How much do you think he paid to get his black box? Where else on Earth has black boxes?
