HongKonger here. I have some friends in China posting similar anti-protest posts on WeChat social media. It's like the news they read has a completely different story than what it's being told in legitimate new sources. The problem of fake news does become very apparent, and I hope people in China can eventually gain awareness or at least start to question the validity of their news sources.
When the fake news is generated and controlled by a government entity, I think the better term is "propaganda".
It seems unreasonable to restrict the term propaganda to government since any organization can produce propaganda, i.e. "information, especially of a biased or misleading nature, used to promote a political cause or point of view."
If it's not from the government, we call it marketing. :-)
This is incorrect. Marketing is not necessarily used to promote political change. There are plenty of examples of propaganda in for-proft and non-profit (yet non-state) media which is clearly propaganda and not marketing simultaneously.
