Be that as it may, from what I read;

Assange wrote on WikiLeaks in February 2016: "I have had years of experience in dealing with Hillary Clinton and have read thousands of her cables. Hillary lacks judgement and will push the United States into endless, stupid wars which spread terrorism. ... she certainly should not become president of the United States."
In conversations that were leaked in February 2018, Assange expressed a preference for a Republican victory in the 2016 election, saying that "Dems+Media+liberals woudl [sic] then form a block to reign [sic] in their worst qualities. With Hillary in charge, GOP will be pushing for her worst qualities, dems+media+neoliberals will be mute.".

Having released information that exposed the inner workings of a broad range of organisations and politicians, WikiLeaks started by 2016 to focus almost exclusively on Democratic presidential candidate Hillary Clinton. In the 2016 US presidential election, WikiLeaks only exposed material damaging to the Democratic National Committee and Hillary Clinton. WikiLeaks even rejected the opportunity to publish unrelated leaks, because it dedicated all its resources to Hillary Clinton and the Democratic Party. According to The New York Times, WikiLeaks timed one of its large leaks so that it would happen on the eve of the Democratic Convention. The Washington Post noted that the leaks came at an important sensitive moment in the Clinton campaign, as she was preparing to announce her vice-presidential pick and unite the party behind her. The Sunlight Foundation, an organisation that advocates for open government, said that such actions meant that WikiLeaks was no longer striving to be transparent but rather sought to achieve political goals.

WikiLeaks explained its actions in a 2017 statement to Foreign Policy: "WikiLeaks schedules publications to maximize readership and reader engagement. During distracting media events such as the Olympics or a high profile election, unrelated publications are sometimes delayed until the distraction passes but never are rejected for this reason." On 7 October 2016, an hour after the media had begun to dedicate wall-to-wall coverage of the revelation that Trump had bragged on video about sexually harassing women, WikiLeaks began to release emails hacked from the personal account of Clinton campaign chairman John Podesta. Podesta suggested that the emails were timed to deflect attention from the Trump tapes.

In 2010, Donald Trump called WikiLeaks "disgraceful" and suggested that the "death penalty" should be a punishment for WikiLeaks' releases of information. Following the dump of e-mails hacked from the Hillary Clinton campaign, Donald Trump told voters, "I love WikiLeaks!" Trump made many references to WikiLeaks during the course of the campaign; by one estimate, he referenced disclosures by WikiLeaks over 160 times in speeches during the last 30 days of the campaign.

In October 2017, it was revealed that Cambridge Analytica, a company working on behalf of the Trump presidential campaign, had contacted WikiLeaks about missing Hillary Clinton e-mails and the possibility of creating a searchable database for the campaign to use. After this was reported, Assange confirmed that WikiLeaks had been approached by Cambridge Analytica but had rejected the approach. WikiLeaks did not disclose what the subject of Cambridge Analytica's approach was.

In November 2017, it was revealed that the WikiLeaks Twitter account corresponded with Donald Trump Jr. during the 2016 presidential election. The correspondence shows how WikiLeaks actively solicited the co-operation of Trump Jr., a campaign surrogate and advisor in the campaign of his father. WikiLeaks urged the Trump campaign to reject the results of the 2016 presidential election at a time when it looked as if the Trump campaign would lose. WikiLeaks asked Trump Jr. to share a claim by Assange that Hillary Clinton had wanted to attack him with drones. WikiLeaks also shared a link to a site that would help people to search through WikiLeaks documents. Trump Jr. shared both. After the election, WikiLeaks also requested that the president-elect push Australia to appoint Assange as ambassador to the US. After The New York Times published a fragment of Donald Trump's tax returns for one year, WikiLeaks asked Trump Jr. for one or more of his father's tax returns, explaining that it would be in his father's best interest because it would "dramatically improve the perception of our impartiality" and not come "through the most biased source (e.g. NYT/MSNBC)." WikiLeaks also asked Trump Jr. to leak his own e-mails to them days after The New York Times broke a story about e-mail correspondence between Trump Jr. and a Kremlin-affiliated lawyer; WikiLeaks said that it would be "beautifully confounding" for them to publish the e-mails and that it would deprive other news outlets from putting a negative spin on the correspondence. Trump Jr. provided this correspondence to congressional investigators looking into Russian interference in the 2016 election.

In August 2016, after WikiLeaks published thousands of DNC emails, it was claimed that Russian intelligence had hacked the e-mails and leaked them to WikiLeaks. At the time, DNC officials made such claims, along with a number of cybersecurity experts and cybersecurity firms.[312][313] Assange accused the Clinton campaign of stoking "a neo-McCarthy hysteria".[314] In October 2016, the US intelligence community announced that it was "confident that the Russian Government directed the recent compromises of e-mails from U.S. persons and institutions, including from U.S. political organizations".[30] The US intelligence agencies said that the hacks were consistent with the methods of Russian-directed efforts, and that people high up within the Kremlin were likely involved.[30] On 14 October 2016, CNN reported that "there is mounting evidence that the Russian government is supplying WikiLeaks with hacked emails pertaining to the U.S. presidential election."[315] WikiLeaks has denied any connection to or co-operation with Russia.[315] President Putin has strongly denied any Russian involvement in the election.[228][229]

In September 2016, the German weekly magazine Focus reported that according to a confidential German government dossier, WikiLeaks had long since been infiltrated by Russian agents aiming to discredit NATO governments. The magazine added that French and British intelligence services had come to the same conclusion and said Russian President Vladimir Putin and Prime Minister Dmitry Medvedev receive details about what WikiLeaks publishes before publication.[316] The Focus report followed a New York Times story that suggested that WikiLeaks may be a laundering machine for compromising material about Western countries gathered by Russian spies.[317]

On 10 December 2016, The Washington Post reported that the Central Intelligence Agency concluded that Russia intelligence operatives provided materials to WikiLeaks in an effort to help Donald Trump's election bid.

In April 2016, WikiLeaks tweeted criticism of the Panama Papers, which had among other things revealed Russian businesses and individuals linked with offshore ties. The WikiLeaks Twitter account tweeted, "#PanamaPapers Putin attack was produced by OCCRP which targets Russia & former USSR and was funded by USAID and [George] Soros". Putin would later go on to dismiss the Panama Papers by citing WikiLeaks: "WikiLeaks has showed us that official people and official organs of the U.S. are behind this." According to The New York Times, both Assange claims are substance-free: "there is no evidence suggesting that the United States government had a role in releasing the Panama Papers."

In 2012, as WikiLeaks was under a financial blockade, Assange began to host a television show that was distributed by Journeyman Pictures and aired on Russia Today Assange has never disclosed how much he or WikiLeaks were paid for his television show.

After President Trump's National Security Advisor Michael T. Flynn resigned in February 2017 due to reports over his communications with Russian officials and subsequent lies over the content and nature of those communications, WikiLeaks tweeted that Flynn resigned "after [a] destabilization campaign by U.S. spies, Democrats, press."

In April 2017, the WikiLeaks Twitter account suggested that the Khan Shaykhun chemical attack, which international human rights organisations and governments of the United States, United Kingdom, Turkey, Saudi Arabia, France, and Israel attributed to the Syrian government, was a false flag attack. WikiLeaks stated that "while western establishment media beat the drum for more war in Syria the matter is far from clear", and shared a video by a Syrian activist who claimed that Islamist extremists were probably behind the chemical attack, not the Syrian government.

In May 2017, cybersecurity experts stated that they believed that groups affiliated with the Russian government were involved in the hacking and leaking of e-mails associated with the Emmanuel Macron campaign; these e-mails were published on Pastebin but heavily promoted by WikiLeaks social media channels.

In April 2017, CIA Director Mike Pompeo stated: "It is time to call out WikiLeaks for what it really is – a non-state hostile intelligence service often abetted by state actors like Russia." Pompeo said that the US Intelligence Community had concluded that Russia's "primary propaganda outlet," RT had "actively collaborated" with WikiLeaks.

In August 2017, Foreign Policy reported that WikiLeaks had in the summer of 2016 turned down a large cache of documents containing information damaging to the Russian government. WikiLeaks stated that, "As far as we recall these are already public ... WikiLeaks rejects all information that it cannot verify. WikiLeaks rejects submissions that have already been published elsewhere". News outlets had reported on contents of the leaks in 2014, amounting to less than half of the data that was allegedly made available to WikiLeaks in the summer of 2016.

So it looks to me, objectively, as if Assange abandoned any type of impartial "transparency" doctrine and instead has been pursuing a political agenda for some time now. Further, it doesn't make a damn bit of sense that his Russian sponsors would allow him to release anything actually damaging to them. Any "leaks" regarding Russian intelligence would have been approved and related to outmoded and/or already-known information, as witness the fact that he rejected the chance to publish actual new information in 2016.

TL;DR- I say bullshit. Assange is a Russian tool and Putin used him to help put Trump in office. Anyone objectively looking at the evidence will see that his "leaks" serve an anti-Western, anti-liberal, pro-Russia agenda.
