Censor its search results? You mean Microsoft cope with the government to filter the result. Great! Today they filter the results. Tomorrow they will share the user data with government.
You are right, Google is not actually blocked by GFW. If you search something the government think it's sensitive (just they think), they will block you from Google for serveal minutes. After that, you can connect to Google again. I say, what the hell is that? Fuck the government.
