The source of millions of documents leaked from Panamanian law firm Mossack Fonseca said his motivation was the "scale of injustices" the papers revealed as he called for a revolution against capitalism, according to a manifesto sent to the German newspaper Sueddeutsche Zeitung and published Friday.
In an 1,800 word manifesto published on the SZ website on Friday, the source, calling himself "John Doe", was critical of banks, financial regulators, tax authorities, the courts, and the legal profession, as well as the media, saying he had offered the documents to several major media outlets that had chosen not to cover them.
"The collective impact of these failures has been a complete erosion of ethical standards, ultimately leading to a novel system we still call Capitalism, but which is tantamount to economic slavery."
He went on to praise others who have leaked secret and sensitive documents, such as Edward Snowden, who revealed details of the U.S. government's mass surveillance program.
"For his revelations about the National Security Agency (NSA), he deserves a hero's welcome and a substantial prize, not banishment," the source wrote.
"Legitimate whistleblowers who expose unquestionable wrongdoing, whether insiders or outsiders, deserve immunity from government retribution, full stop," he said.
The documents cover a period over almost 40 years, from 1977 until last December, and purport to show that some companies domiciled in tax havens were being used for suspected money laundering, arms and drug deals and tax evasion.The source stressed that he did not work for any government or intelligence agency and concluded his manifesto by saying "inexpensive, limitless digital storage and fast internet connections" should help digitize the revolution against income inequality.
