My only real objections...
My only objections in the matter are that:
He was threatened with a US military trial initially.
By US definitions he is a terrorist, and the US is a country with an established reputation for sending convicted and suspected terrorists outside the US for "interrogation".
After 10 years there's going to be no way to dispute the evidence.
All of his "Great Digital Break In" efforts were only possible due to the complete failure of a US government organization to follow even the most basic of security standards on machines both accessible to the internet and that contained "sensitive" information.
What he did, amounts to digital vandalism. The equivalent of walking into a house that has it's door swinging wide open and after rummaging through the drawers spray paints "Noob! Lock yer doors! That's why it has locks!" on the walls. It's something you slap someone upside the head for and have them pay reasonable compensation for the damage and suffering. Instead he's facing anything and everything up to over a century in the US prison system.
