First, the straw man :-) Mueller explains the "technical protocols may and should enable/help human rights" position (the one from HRPC documents). #IETF99
Now, the critique. 1) the Internet is already designed, we cannot change it in depth. 2) human rights can be in conflict with each other (privacy vs. accountability, which is required to protect people from aggression, or freedom of speech vs. protection against libel) #IETF99
Also, it is very difficult to predict human rights impact at the moment of [protocol / system] design. Things do not go the way you think (specially when people actively try to "subvert" or hack them). #IETF99
