That said, I do think he absolutely deserved to be released, not because he didn't deserve to be locked up in the first place, but because he's clearly been rehabilitated and has done great work during his time in prison. All that considered, ten years seems like a not unreasonable prison sentence for what he did. I hope he'll continue to do good when he's released.
Those allegations were used to deny him bail and influenced public perception, they were not part of his formal conviction or sentencing.
He was convicted on non-violent charges related to operating the Silk Road website, including drug distribution, computer hacking, and money laundering.
Does this change your opinion of sentencing being well-deserved?
The U.S. is rather unique in providing a right to jury trials for most--in practice almost all, including misdemeanor--criminal cases. And this is a major factor for why sentencing is so harsh and prosecutions so slow in the U.S. In myriad ways the cost of criminal trials has induced the system to arrive at its current state favoring plea deals, with overlapping crimes and severe maximum penalties as cudgels. Be careful about what kind of "protections" you want to impose.
