The UK trial was not on the rape charges (there was no permitted discussion of the evidence or total lack of it). The ruling was over whether the UK was bound to extradite given the Swedish government's refusal to interview Assange in England or indict him in Sweden. The tortured legal conclusion was basically that the UK couldn't definitively conclude the Swedes were acting in bad faith, and they couldn't be entirely sure that Assange was only being extradited for questioning (technically illegal).

As far as the Swedes go, the Swedish government discussed the case when it closed it for the first time. If the government hasn't been public about the case since it was re-opened by a political appointee, perhaps it is because there is zero evidence against Assange. We know this because the pretext for re-opening the case was the "discovery" of new physical evidence (a broken condom) that lacked any of Assange's DNA. This is all public knowledge, btw. Funny how it isn't discussed much in the press.
