Here is tptacek saying that Assagne was dishonest and irrational when claiming to fear extradition to America: https://news.ycombinator.com/item?id=11043329
Go through his comment history and survey what he's been saying about Assange over the years. It's pretty egregious.
Since he was forced out of the embassy into the arms of UK police, and never planned to go to Sweden, I don't think we'll ever know if he would have been extradited from Sweden (or on route to Sweden) or not.
Tptacek was making a point that's a bit more nuanced than you seem to give credit for. He hasn't been "proven wrong" by the UK allowing US to extradite Assange.
Let's be real here, he never would have made it to Sweden. One way or another, Assange's fear that leaving the embassy would end in him in an American courtroom was neither irrational nor dishonest.
I have no idea why the poster above you is choosing to attack him specifically, though.
Titled Definition of paranoia: supporters of Julian Assange. Feel free to read the text in the contest of today's news.
"More pertinently, Greenwald and the rest of Assange's supporters do not tell us how the Americans could prosecute the incontinent leaker. American democracy is guilty of many crimes and corruptions. But the First Amendment to the US constitution is the finest defence of freedom of speech yet written. The American Civil Liberties Union thinks it would be unconstitutional for a judge to punish Assange... From the 1970s, when the New York Times printed the Pentagon Papers, to today's accounts of secret prisons and the bugging of US citizens, the American courts "have made clear that the First Amendment protects independent third parties who publish classified information". Maybe the authorities could prosecute Assange for alleged links with hackers. I don't know – unlike Assange, I cannot see the future. But why would they bother to imprison him when he is making such a good job of discrediting himself?"
And for some reason having that opinion got my original post flagged and collapsed by default, even though I have a positive score...
As for the link, I mostly made a lazy search just to provide a link to "news articles, politicians, political pundits". If there was multiple people on HN claiming he was not going to get charged by the US then I would expect to see similar opinion outside HN. I thus tested the theory.
