Earlier quoted context omitted.
If a "credible" (read: state-approved) news organization had released those emails, would you have the same thoughts toward them?
A credible news organization would have tons of fact checkers and editors to make sure the relevant facts made it in to any article they wrote. They wouldn't, blindly, release tons of unedited emails, including some that were doctored to make the DNC and the Clinton Campaign look bad. Doesn't need to be state-sponsored (and most news organization aren't "state-sponsored" ... unlike RT, for example) to be credible.
If true, that's the point at which Assange and Wikileaks departed from the path of legitimate journalism.
