All the craziness about preventing American internet companies from dominating the Domestic Chinese market makes total sense now, doesn't it? If the Chinese economy had been built around Facebook, Google etc. the US would have a lot of leverage, since they're all US-based companies and _must_ comply with whatever US Government asks them to do.
Can you tell me with a straight face that the CIA, NSA etc. do _not_ have active espionage activities in China? Do you think valuable intellectual property and state secrets exist only in the US? That as a result of these activities, the Chinese Government has not also lost lives?
Do not buy so easily into propaganda. Nations will promote themselves as the only "Good" nation to their own people throughout the world. Because the US is a democracy, the US Government has to be very careful and frame the narrative in a way that's not an outright power grab.
