If you are accusing me that I'm preaching and not following my own words, that is a big assumption on your side.
This is what I'm accusing you of. How has Chinese affairs changed for the better after Google?
Of course, all things above are not simple. There is the prisoners dilema "if not me, then someone else will do it", and "if it is me, I can prevent even worse from happening", but there is also the "slippery slope" where making small concessions leads to more and more concessions. So, everyone make there choices and we all leave with the consequences.
You're right that this is beyond the scope of Google in the same way that it's beyond the scope of any individual. But together humans can slowly influence other humans and doing the right thing might be a tiny influence but eventually these might add up.
