The online whistleblower WikiLeaks says it has won a significant victory in challenging a financial blockade imposed by major financial firms. MasterCard, Visa, PayPal, Bank of America and others have blocked WikiLeaks’ donations since it began publishing classified U.S. government diplomatic cables in 2010. An Icelandic court has now ruled Visa and Mastercard broke laws in stopping WikiLeaks’ payments and has ordered the companies’ local partner to resume processing its donations.
