If you aren't breaking the law, the government won't be looking for your data, and won't ask Google/Yahoo/Bing/AltaVista or other search companies for your data.
Welcome to China, host country of IETF 79, the first IETF meeting that will break the record of VPN tunnels ... Also, what law ? what government ? Ask Yahoo about what happened in France about some collectible items, ask Dow Jones for distributing news in Australia that some guy didn't like, ask Google about providing search results that famous people don't want to see everywhere. On the other hand, name it Google, Yahoo, Bing, or whatever, their biz model is to make money based on information they collect about you (even in an abstract form) or that put through your throat as advertisement, but keep in mind that most of the time there is only one source for such information: You ;-) If you don't like it, get isolated, (I was going to say move to Mars but it won't work since it's already on Google's master plan and Vint's interplanetary network vision) move to Wassila and enjoy fishing alone.
