Sure, I was just pointing out that they're using the brute-force approach now
but presumably at some point will stop blocking when they've implemented a way
to bypass it. My guess is that since the GFW uses blocklisting (of known
sites/pages) all they'll need to do is fingerprint the sites they want to
block and take it from there. Stuff like the ConceptDoppler work
("ConceptDoppler: A Weather Tracker for Internet Censorship" out of UC Davis -
that was one paper I do remember :-) showed that they don't try and block
everything but just enough to let you know it's happening and they're watching
you, which the fingerprinting approach is fine for.
