Actually, what I said was it was a complex issue, with many factors I cited (including some you name) but that the my final analysis says Google took the wrong course. Many Google employees believe this as well. Even Google management has said that they see believe that positions like mine are valid to hold.

So I'm not sure why my saying that their course is, on balance of a number of factors I cited wrong, is some sort of absolute assertion. How should I rewrite it?

The question of "If we don't do it, somebody else will, and more, they will do it worse" is also a complex one. When this is argued the argument always seems fairly rational. Yet when viewed from a distance, it usually ends up wrong. So much evil in the world gets done for that locally rational reason. So if this argument is ever right, how can you identify the times when it is?

I think you will find that many, many Chinese (almost surely greater in absolute numbers than the entire population of South Africa) want action against the government. Certainly all members of Falun Gong, huge numbers of Tibetans, etc. All those who marched in Tien an Men whose pictures Google won't show. And how many who saw the pictures of the tanks and are scared to stand up -- I don't know.
