Stepping into the murky quagmire of ethics, I could argue that the 2 to 4 million Vietnamese who died defending Vietnam from American invaders is much worse than censoring the Internet. That Internet is largely made by those same murderers and they have the largest spy agency in the world, the CIA, trying to break in and spy on seemingly everyone, so it must be filtered.
One could also argue that enforced family planning allows for centralized natural resource and pollution management. China per capita pollutes much less than the United States.
Again, I am not taking or defending these arguments, but it is easy to see that it is not clean and objectively true that one nation is always ethically superior to another.
