Actually, focusing on attacking china is a big mistake of this admin. It accelerates the decline of US hegemony as we know it. The best strategy for US is to maintain the current world order with China. Only the weaker countries "behind" US/China, e.g. India/Japan/Vietnam/Taiwan, would want the two countries to fight it out so they can benefit. And there are people in the US who believe a trade and technology war with china is easy to win, which are proven wrong.
The trend where large Internet platforms control political content propagation will intensify, and prevail in the end. Elites all over the world will not easily cede control of important narratives, which they wield in traditional media (news paper, TVs). For me, deleting COVID misinformation is ok. Blocking Trump's tweet on the election results is a bit more dubious (why not leave it to the people to judge, which are given the right to vote anyway?). And we will see more of these in the coming years.
I think many people have similar ideas around the same time: Charpentier, Doudna, Zhang, Šikšnys etc. Zhang is the lastest to publish the result, but got the furtherest along in applying to human. I don't think anyone believes Zhang's work is based off others.
