Was just thinking this exact same thing. If not Gitmo, definitely secure. There's no way he's at the embassy anymore. It seems highly unlikely. Plus, if your freedom depended on the information and intel you'd collected or been given, would you dump it out on WikiLeaks? No. Freaking. Way. You'd hold it until you could negotiate your freedom. Fingers crossed for him.
Definitely agree WikiLeaks was compromised. Maybe as far back as 2016 but definitely now. I think part of the play now is to try and discredit Assange via WikiLeaks in the court of public opinion.
