Useful discussion here and the article from google here There are plenty of sides to the story, but history tends to judge harshly from a moral standpoint those not willing to make a stand on this sort of thing. Western nation’s compliance in the persecution of the Jews in pre-WW2 for instance.
But then I suspect Google is not thinking about that, its all about the 1/5 of the worlds population they could make money from - which is at the core of all dealing with China.
Google is NOT about sharing information, it’s about monetisation of click through their very popular search engine. Remember that everytime you search.
