I was talking about the incident that happened prior to the events you posted.

In 2014, the company hired to monitor Assange warned Ecuador's government that he was "intercepting and gathering information from the embassy and the people who worked there" and that he had compromised the embassy's communications system, which WikiLeaks called "an anonymous libel aligned with the current UK-US government onslaught against Mr Assange". According to El País, a November 2014 UC Global report said that a briefcase with a listening device was found in a room occupied by Assange. The UC Global report said that proved "the suspicion that he is listening in on diplomatic personnel, in this case against the ambassador and the people around him, in an effort to obtain privileged information that could be used to maintain his status in the embassy." Ambassador Falconí said Assange was evasive when asked about the briefcase.[291][292]

It was one of the first events that started to raise the hairs of people in the embassy.

As far as the imf loan, it seems pretty circumstantial. Tbh I just don't think that the new leadership wanted to continue to pay millions of dollars a year just to watch the guy stir up trouble.
