Assange is for some reason decided to leave the embassy of Ecuador, maybe 7 years in house arrest it was too much for him. When I say he decides it, I think of his actions against Ecuadorian President Lenín Moreno in which some documents have been published on WikiLeaks, where the president is accused of a corruption scandal.
You're wrong, Wikileaks didn't publish the documents. The INA Papers, the documents accusing Lenin of corruption, were published in a website called inapapers(dot)org. Wikileaks only tweeted (a month later) about the allegations of corruptions against Lenin citing the aforementioned website. Hell, the whole thing started because some ecuadorian journalists started digging about Moreno's offshore companies.
Because of this tweet, the Ecuadorian govt
assumed it was Wikileaks who leaked the documents and used it as an excuse to expelled Assaled from the ecuadorian embassy, probably to avoid any backlash from the US against Lenin Moreno in case the corruption allegations are true.
