Neither of these sentiments are true.
There is a material difference between 'Whistleblowing' and 'Stealing and Releasing Data Because You Want To'.
Those releasing documents regarding arbitrary imprisonment of people because of their ethnicity are 'Whistleblowers'. I would argue that the release of the video showing US accidental killing of Journalistgs in the friendly fire incident, may fall under that.
But the diplomatic cable leaks I don't think constitute whistle blowing.
"Laws are basically just threats,"
Total rubbish, I can't fathom that someone would believe this.
The Law is the most foundational aspect of civilization, probably more important than democracy itself.
It's a set of codified rules that we roughly agree upon, or at least are aware of, that we are all equally subject to, not one above the other - or at least it's supposed to be, and when it's not, we consider that a form of corruption.
Assange is possibly guilty of the crime of breaking into private government systems to release arbitrary data to the public, which is probably a crime.
When the trial starts, we'll get to see the evidence, one of the advantages of living in a Western Liberal Democracy is that most of this information is available to anyone, another key aspect of a functional Judicial System BTW.
