Hate to be "that guy", but public blockchain technologies are another strong tool that people have for resisting censorship [0]. It's much, much harder to nullroute blockchain traffic as opposed to nullrouting a website with information you want to censor. It's also very clear that the CCP is afraid of such technologies [1]
The rub is of course, this censorship-resistance being predicated on the consensus mechanism of a blockchain not being concentrated in one country.
