Wikileaks is a news organization and has not done anything that a free press has not always done. Julian Assange is a citizen of Australia and Ecuador. He is not an American and thus cannot be guilty of treason. Yet Washington is believed to have used a grand jury to concoct such a case against him.
The new president of Ecuador is not the strong and good man than his predecessor was. Under Washington's pressure Moreno is making life in the Ecuadorian embassy as unbearable as possible for Assange in an effort to force him out into British hands. Responding to Washington's pressure, the British government will not honor his asylum, which prevents Assange from being able to leave the embassy.
There is no presence of "democratic values" in this affair. It is a repeat of the Soviet Union's treatment of Cardinal Mindszenty, only it is Washington, not Moscow, who is stamping on the face of freedom. https://www.paulcraigroberts.org/2013/07/23/role-reversal-how-the-us-became-the-ussr-paul-craig-roberts/
The Australian government, also in deference to Washington, has done nothing to help Assange. Australia, like every other vassal state, puts Washington's interest ahead of both law and the interest of citizens.
This week there were protests in Australia in support of Assange. However, Western governments are now so far removed from citizens who are today little more than subjects that it is unlikely that anything short of revolution can restore accountability to governments in the West.
"Western democracy" has become an oxymoron. This article http://www.informationclearinghouse.info/49687.htm by Mike Head shows the disdain that the Western elites have for free speech, freedom of the press, truth, and the rights of citizens.
