You've pointed out some of the US's flaws, but pointing out that one's critic has flaws doesn't justify the shamelessly blunt repression that the Chinese government prides itself on.
If the perception is that US cultural imperialism is so strong that something as extreme as the Golden Shield is necessary, well, I don't buy it. Regardless, it'd be better to solve that problem itself (international corporations that prey on countries via neoliberalism). But the Golden Shield is more about the Chinese Communist Party maintaining power -- hence the drama around "Tiananmen" searches. The defense of the Golden Shield that's based on a criticism of Western influence seems like misdirection and, apparently, successful propaganda.
