WikiLeaks fetes 10th birthday in defiant form

WikiLeaks celebrates its 10th birthday on Tuesday defiantly proud as the pioneer of online leaking platforms, while its controversial founder vows to pursue its work despite widespread criticsm.

An anniversary party in Berlin will commemorate the 2006 registration of the domain name wikileaks.org, and founder Julian Assange will address a press conference of his German supporters by video link at 10:00 am (0800 GMT).

But Assange has at the last minute cancelled what would have been a rare public appearance on the balcony of his 18-square-metre room in the Ecuadorean embassy in London, citing security concerns.

But he remains dauntless. "Adversity has hardened us," Assange told German news weekly Der Spiegel in a weekend interview. "We believe in what we are doing .. If you are pushed you push back."

Ten years after it was founded, the site has faced growing charges that it is manipulated by politicians -- either by recycling documents provided by Moscow, or by allegedly serving the interests of Donald Trump in the US presidential election race.

No self-censorship

"We're not going to start censoring our publications because there is a US election," Assange told Der Spiegel in an interview, published in English online.

WikiLeaks launched in January 2007, with Assange saying it would use encryption and a censorship-proof website to protect sources and publicise secret information.

The site has since published more than 10 million leaked documents.

It first caught the world's attention when it released manuals for prison guards at Guantanamo Bay.

But it really hit its stride in 2010, unveiling logs of US military operations in Iraq and Afghanistan and a video showing a US helicopter crew mowing down a group of unarmed civilians -- including two journalists -- in Baghdad.

That same year it also published a cache of diplomatic cables from US embassies around the world, deeply embarrassing Washington.

"The most important single collection of material we have published is the US diplomatic cable series," Assange told Der Spiegel.

'Power-obsessed' 

But 2010 also saw grave blows to the organisation.

Assange was accused of having sex with a woman while she was asleep after the two met at a Stockholm conference.

The white-haired WikiLeaks founder took refuge in the London embassy of Ecuador -- which granted him political asylum in 2012 after he lost a legal battle to block his extradition to Sweden.

The 45-year-old has always maintained the allegations are false and has refused to travel to Stockholm for questioning due to concerns that Sweden will hand him over to the US to stand trial for espionage.

But Assange's abrasive style and insistence on publishing unredacted documents quickly grated on colleagues and journalists who worked with him.

"If an Afghan civilian helps coalition forces, he deserves to die," Guardian investigative journalist Nick Davies later recalled Assange saying in an argument over whether to remove names from the war logs.

Snowden, Panama Papers 

In 2013, former US National Security Agency contractor Edward Snowden chose to leak documents exposing intelligence agencies' mass surveillance programmes to selected journalists instead of offering the trove to WikiLeaks. And many later whistleblowers have turned to other organisations.

The International Consortium of Investigative Journalists this year published stories based on data dumps from tax havens Panama and the Bahamas, while environmental group Greenpeace in May released documents from negotiations over a controversial US-EU free trade deal.

WikiLeaks caused a fresh stir in July when it leaked emails showing US Democratic Party officials favouring Hillary Clinton over left-winger Bernie Sanders in presidential primary elections, forcing high-ranking party members to resign.

Assange himself is unmoved by criticisms of his organisation.

"We believe in what we're doing," he told Spiegel. "The attacks only make us stronger."
