>Maybe I'm lacking in morality but I don't understand how serving censored content to people that already live in a society where the content is censored is considered evil.

If only was just a simple web search with some results removed maybe it won't be such a big deal, but consider this:

- Google does this for big money, so they want to sell ads and maybe other services in China

- To make money from ads Google tracks people and collect their data

- By law all this data from China will have to be hosted in China and the government can access it whenever they want, no warrens needed, no way to opose such a request

So Google will track and collect data and hand it over to China to do whatever, I imagine they could do an SQL query to find who searched some "illegal" keywords and send them to work camps or worse.

I think is normal as an employee to tell your bosses that you don't want to work on tools that will be used for harming others and try to convince them to find other contracts since they have already enough money they could maybe be less greedy.
