"To offer this service to the people of China Google will have to abide by the law. Google is not objecting to the law because it wants to provide the service to the Chinese population."
Yes, I never said otherwise.
"Which are the heads of Google who went ahead to develop this service."
And the people who work for them.
"What are the absolutes of morality/rightness."
You've moved the goalposts here. I was disputing the assertion that "moral and right have no meaning". I was not asserting that there was such a thing as an "absolute morality".
"This is others complaining about it."
This is the workers trying to correct what they see as an unacceptable situation. I don't see the problem with that at all -- we all have the right (and duty) to speak up and act about things we find unacceptable. They're doing so because Google has, in the past, been a company that promoted and valued a certain set of ethics, and this project is in opposition to that.
I do think that really, this is the employees waking up to the fact that they don't work for the sort of company that they thought they worked for, and they are trying to avoid making the hard decision between compromising their own values or quitting positions that they used to value.
Personally, I think the best move they can make is to quit (Google isn't going to change, after all), but when you're very invested, it is a gut-wrenching thing to face. So I have sympathy for them.
