Well, really, back then, what could we say we knew about the guy? He wasn’t fond of the US, he knew a decent amount about computers, presumably, and released some US secrets that were leaked to him.
Consider what we know about him now - That he’s a racist, anti-Semitic, sexist, alt-right white-supremacist loon and conspiracy theorist, hiding out in an embassy to avoid going down for a rape charge, claiming credit for things he didn’t do, and perfectly happy to put other people in danger for the sake of his ego, like the time he doxxed practically every woman in a country that really isn’t terribly nice to women.
His leaks can’t be trusted, because we know he modifies, editorializes, and whithholds parts of them them to suit his own purposes(in fact, he admitted as such around the time of Collateral Murder in an interview with Colbert), and we know that he’s been happy to take both information and money directly from the Russian government, and that the leaks his organization come out with are almost always against enemies of Russia, or to advance Russian interests - to the point of coming out against the Panama Papers, because they revealed some Russian secrets.
And to cap it all off, we have a number of people who’ve known him in the past who have said about pretty much everything but the Russia stuff, “Yeah, he’s basically always been this way, he just used to bother hiding it because he knew it wasn’t publicly acceptable.”
So, in his case, it seems less a case of “Which is bad”, and more a case of “It was always bad, we just didn’t know before.”
