Canadians To Douse Chinese Firewall

FrenchyinOntario writes "Researchers at a University of Toronto lab are getting ready to release a computer program called Psiphon, which will allow Internet users in free countries to help users in more restrictive countries (like China, North Korea, Saudi Arabia, etc.) to access the Internet by getting past the firewalls and getting around "rubber hose cryptoanalysis" which is a drawback of other anti-firewall programs as it reveals a user's tracks if discovered by authorities. Operating through port 443, Psiphon will allow users in monitoring countries the ability to send an encrypted request for certain information, and for users in secure countries to send it back to them. The UofT's Citizen Lab hopes to debut Psiphon at the international congress of the free speech group PEN in May."

      An interesting op-ed piece I read today suggested that this is a war between Freedom and Fundamentalism. As we are seeing with the current Congressional Hearing involving Google, Yahoo, MSN, etc, Capitalism doesn't much care either way for Freedom or Fundamentalism, but is calculated solely on risk and reward - even if you purport to "do no evil". To look at Western politics around the world, and more topically the effects of those Danish cartoons which are not being published, most people don't have much of an opinion here either.

      As has been said here previously, free speech only continues to exist when people exercise it. There is much uninformed opinion in the world, and even our leaders are increasingly elected on the basis of limited amounts of tightly controlled information. Does this lead us closer to Freedom and Democracy?

      The Fundamentalist has a narrow agenda, is easily inflamed, readily invokes fear to reinforce their message, and has little respect for all who disagree. Those who favour Freedom will always suffer at the hands of Fundamentalists - Freedom is Fundamentalism's single worst enemy, and the uninformed Free will happily trade minor freedoms for any illusion of security against perceived threats. Against this slow but steady onslaught, Freedom's only weapon is exercising available freedoms - even to risk one's own life if necessary.

      While it is the duty of the Free to selflessly attempt to liberate the oppressed, Capitalism guides us to minimise risk now and build short-term rewards. In the face of rising global Fundamentalism (whether Christian or Muslim, Capitalist or Socialist), Freedom dies by a thousand cuts.

      It will do us all good to see more fearless initiatives like this one from Canada.

      Are you not aware that the Chinese regime has, since their invasion of Tibet in 1950, systematically destroyed all aspects of Tibetan life: Tibetan national identity, unique Tibetan language and script, unique Tibetan buddhism... not to mention turning Tibet into a giant Chinese nuclear missile site and nuclear dumping ground, ripping off Tibetan natural resources and promoting Chinese migration into Tibet, turning Tibetans into a rightless and stateless minority in their own country!? Preserving culture?? Maintaining social order?? While a large number of ethnic Chinese may find the CCP's dictatorship and the accompanying censorship as an acceptable tradeoff for being finally able to engage in "bourgeouis" activities, at least their party-approved mainstream culture hasn't been under systematic eradication since the end of the "Cultural Revolution" around 1976. If the majority is willing to remain under dictatorial rule and not care about the rights of others or the imprisonment and torture of innocent freedom-caring people at the hands of their regime, even that could be argued to be their right. Chinese accepting to live under Chinese mob rule.

      However their regime nor the Chinese as a nation have absolutely no right to hold their neighboring Tibetan and Uigur nations under brutal Chinese military occupation with the "Final Solution" looming close to those oppressed non-Chinese peoples.

      OK. Think for moment about the French, and then spare a moment for the Tibetans who are guaranteed to face imprisonment and quite likely torture as well for simply speaking against the ongoing Holocaust in Tibet, or just saying "Tibet should be free again"! In China, the regime has "laws" (and plain all-pervasive and ruthless paramilitary machine) that severely punish people for challenging in any way the regime's most transparent and ridiculous falsehoods denying the ongoing Holocaust...!

    As a Canadian, although I do sympathize with those in China trying to get around their censorship, I am concerned with one country developing a tool with the explicit stated goal of trying to undermine an internal regulation of another country. In effect, it provides the user with information which is not allowed in their own country.

    What would the Canadian government think if people in countries with different drug laws started intentionally mailing their drugs, which they consider legal, into Canada? Better yet, what would Canada think if such an action was sponsored by the government of the offending country (Psiphon is coming out of a publicly funded university in Canada).

    As another example, currently a hot topic up here is gun violence. Many of the guns get into Canada from the US, where the gun laws are not as strict. Certainly, and rightfully so, the Canadian government would be offended if the US government funded a program with the goal of getting more guns into Canada.

    I agree both drugs and guns *can* be much more harmful than information, but if the consequence of having that information is jail sentence in a Chinese prison, then enabling them to access it is something that should not be taken lightly.

Stop limiting everybodys freedom on the net in order to make some often rather futile moves against online pedophiles. Use all those misspent efforts to go after the real life pedophiles and those helping them (sleezeball photographers making kiddie porn etc.). This will do much more in preventing harm to children and it will cut off the feed of kiddie porn at the source.

    A much bigger threat to mankind are the repressive regimes bent on controlling how people think. Making it possible for free thought and expression to spread and flourish and thus paving the way for those regimes to fall, are far more important than preventing a few pedophiles from sharing their filth.

    The french revolution took maybe 100,000 lives (40k alone went to the guillotine), in a country of about 40 mio. people. Now imagine the body count in a 1200 mio. people country. Add modern firearms and tanks. 3 mio.? 4 mio.? maybe 5 mio. people could die during an all-china civil unrest.

    If the chinese leaders are wrong, they are oppressive tyrants who've killed thousands. But if the free speech advocates are wrong, they are rebellion initiators with millions of dead on their consciousness.
