Because nothing we saw in those videos has happened anywhere else in the world. They showed people being welded inside their apartments, young people screaming and coughing in the emergency rooms like they were being tortured to death, and people dropping dead in the streets and projectile vomiting. And all were suspiciously "leaked" at the same time, by random Chinese Twitter accounts.

And now that every country has the virus, we aren't seeing those videos anymore or hearing anything about it from them. They literally went quiet the moment everyone locked down.

It's almost as if they know the show is over, they did their job by scaring the entire world into destroying their economies, no need to keep the act going. They are masters at media control and manipulation, I believe they could have orchestrated this.
