Snowden actually got a lot of support. I remember that even some high profile corporate executives expressed support... Though a cynical take on that would be that it was just to cover their own asses because they wanted to make themselves (and their companies/platforms) look like victims of government surveillance as opposed to facilitators.
The support was indirect but it helped to divert attention away from the 'criminal' aspect of Snowden's actions... Which is more than Assange ever got.
I don't really think this is true. I view him unfavorably because he avoided extradition on rape, sexual assault, molestation, and sexual coercion charges until time ran out.
I sympathize with him for cracking the admin password to help Manning get documents anonymously, but it doesn't overshadow that he'll never have a day in court for the women who brought credible criminal allegations against him.
I think this is true of other whistleblowers too. The "good" ones that break no laws and do everything by the book... but in the end, no one wants to hire them.
