The Chinese government has had a lot of success blocking Tor (and VPNs) most recently. You may know that all of the normal relays are publicly listed in the Tor directory, making them trivial to block by IP address. That will then require Tor users to do extra work to find bridges or configure pluggable transports for censorship circumvention, which most users may not be motivated enough to do. Censors can also try to fingerprint and block some of the circumvention methods. In sum, Tor is not trivially or resoundingly winning the censorship arms race, even though it has some good work on censorship circumvention that's often effective in particular countries. Some good background on this is in https://www.bamsoftware.com/papers/thesis/ |
