In December 2010 three of the world's biggest payment providers, Visa, Mastercard and Paypal, cut off funding to WikiLeaks. Ten months later, Julian Assange has announced the whistleblowing site will suspend operations until the blockade is lifted - and warned WikiLeaks does not have the money to continue into 2012 at current levels of funding. The banking blockade against WikiLeaks is one of the most sinister developments in recent years, and perhaps the most extreme example in a western democracy of extrajudicial actions aimed at stifling free speech. Payment companies representing more than 97% of the global market have shut off the funding taps between WikiLeaks and those who would donate to it. Unlike many of the country's leading corporations, WikiLeaks has neither been charged with, nor convicted of, any crime at either state, federal, or international level. Visa and Mastercard are already inescapable. As the world becomes ever-more digital ... they will become still more pervasive. If they are allowed to cut off payment to lawful organisations with whom they disagree, the US's first amendment, the European convention on human rights' article 10, and all other legal free speech protections become irrelevant. Those who value free expression, whether they like WikiLeaks or loathe it, should hope it wins its current battle.
