Would ending the Great Firewall truly end the dictatorship? (结束防火墙真的会结束独裁吗?)

Not 100% sure.

In Russia (俄罗斯), for example, the Internet is relatively free, but the government controls most professional media, which is what most people end up seeing, by suing dissidents media out of business.

But on the other hand Russia is already much freer than China.

Although I don’t like them, I can’t deny one thing: the commies are smart, and when they do something (e.g. censorship), it tends to keep them in power.
