I think there's almost no chance. SBF is a perfect example of someone to throw the book at. He's effectively Madoff 2.0, the people everyone from the lowly to the elite hate.
Ross Ulbricht is a very unique, interesting case. I don't for a second believe that Trump has any moral imperative with pardoning him, but his sentence for the crimes he was prosecuted for was very clearly unjustly large in an extensively murky case. There's also a whole slew of benefits to Trump for pardoning him - it's largely perceived as very pro-crypto, pro-libertarian (ironic), etc.
In any sane democracy I would agree with you. But this POTUS has pardoned 1500 people that actively participates in an insurrection, some of who hurt and even killed police officers. He's pardoned a the Dread Pirate Roberts.
All of those people were perfect people to throw the book at.
From what I read, the Ulbricht pardon was part of a deal at the Libertarian National Convention. So it's just business as usual.
Broken clocks and all that. I entirely agree that he may have a potential muder conviction on his case, but they instead threw the book at him for a much lesser crime for a way too large sentence. Especially if we compare it to the War on Drugs.
