I want you to note something that is not generating outrage on the left. The Chinese communist party and the information ministry of China are using Twitter to spread disinformation about the virus. On a daily basis, the propaganda masters of China are on Twitter telling people that the United States is to blame for the virus. There are very few Democrats complaining.
Facebook is the one tech giant that refuses to do business in China. It has no Chinese operations. Twitter is blocked in China, but would desperately love to be there. In 2016, Democrats blamed and savaged Facebook for Russians spreading misinformation on their platform. It turns out it was not a significant amount of misinformation, but there was some. Democrats, to this day, are attacking Facebook. But they are awfully silent about what Twitter is doing.
It is not a coincidence that Facebook has increasingly treated conservatives and progressives the same — mostly being hands-off and allowing all political speech. Twitter, on the other hand, is increasingly antagonist towards conservatives and conservative values.
