Notice the vast variety of files Wikileaks was publishing early on.
This practice was eradicated when Assange abandoned much of his peers to go full anti-west love-Putin. Now you know every single release is going to be agenda driven, with the leak timed to benefit the party that gave it to Assange.
About that selective bias, some news today:
“Stone claimed to the [Trump] Campaign as early as June 2016—before any announcement by Assange or Wikileaks—that he had learned that Wikileaks would release documents damaging to the Clinton Campaign.”
Corroborated by multiple witnesses, redacted by William Barr.
Are you commenting on all of the WikiLeaks, meaning, have you read every publication/selections from every collection?
Or are you basing this perception based on what stories a bunch of bloggers decided to key in on because Trump happened to be in their spotlight at the time?
