I believe this proposal started long before E-PARASITE, SOPA and similar (pending) legislation, but it has become relevant given the current SOPA situation. dot-bit (namecoins) has the potential of circumventing the DNS-censorship that SOPA might enable.
Also, its sister technology, bitcoin, has the potential of circumventing the payment-processor (ex. MasterCard) type of censorship. (See how wikileaks is being shutdown/censored)
