Like to admit it or not but the USA still has a functioning system of laws and an independent judiciary. Disagreeing with those laws or the judiciary is very different from living in a state like Russia.
Aaron Swartz, Eric Snowden, Bradley Manning et al all knew the laws they were breaking and the likely consequences. Those laws are harsh yes, but they chose to fight them by breaking them - they didn't have to. There are legal avenues for whistleblowing, regular criminal prosecutions of government corruption etc.
It's also blissfully ironic that this article praises Russia "following the law" when it comes to refugee status, yet the UK's similar stance re Assange and why he's being kept inside the embassy is lambasted on here.
