Yes, you are right. I can see how requiring your name when rating an android app or commenting on a YouTube video would drastically affect human rights activists in China. I am sorry if you are expecting a company whose business model revolves around selling user information to protect your anonymity, then you are going to have a bad time. A company like Google is going to comply to government request for information, that is why we have services, utilities, and tools that protect your anonymity online. Google is doing nothing wrong by asking for your name (they probably have it anyways). However, if they where blocking search results to prevent your anonymity, that is a different story altogether. In a case like China, it is the government that is doing the blocking and Google has no choice in the matter if they want to do business there.

I was addressing your comment about "take responsibly for what you put online". We need the ability to be anonymous because sometimes things that need to be said simply can't be said if you're not anonymous.
