If you want to publish your own newspaper, you can. Nobody will stop you. Start your own online video news service, weblog or nes site - nobody will stop you. Post whatever you like to Reddit, or any other discussion platform.
In China and Russia you cannot do these things. Published mdeia are strictly monitored and censored. The state employs thousands of astroturfers to flood social media with pro-government messages, trash anti-government messages and even directly hook into messaging platforms to delete messages the government don't like. Be persistent at it, and you'll get a visit from the police, or just get beaten up a few times.
The very fact that the BBC could publish that report, and Noam Chomsky could publish his book, is strong evidence for freedom of expression in the west. There are no such equivalent sources published in Russia and China exposing their government's manipulations. Why do you think that is?
