On the one hand, these researchers are (admirably) trying to circumvent censorship put in place by repressive regimes. Of course, these regimes do not even care about Tor as they do not have the resources to attack it. Tor-Schmor, they will just throw a switch and cut off all internet access, period. On the other hand, we have sophisticated western organizations like the CIA and FBI that are hellbent on breaking Tor for the ostensible purpose of rooting out child porn and terrorism.
Who will win is anybody's guess.
