Yes; I lost a lot of respect for Wikileaks after that. It seemed as if they'd branched out into the propaganda business. I wonder what made them change direction after so long.
This was brought up on The Colbert Report's interview of Julian Assange [1]. His response was that they where provided the video under the condition that they'd try to maximize its political impact to the best of their ability. I don't think their strategy was the best way to fullfil that goal (precisely because of the blatant political slant), but that's their stated motivation. 1. http://www.colbertnation.com/the-c…
I never really got upset about Wikileaks providing commentary, because I never had the illusion that they were going to be impartial. Don't be lazy, apply some critical thinking, listen to different sources. Leaks are in their nature untrustworthy. Even intelligence agencies with all their highly educated analysts get things wrong.
Finally if you stop supporting Wikileaks because you don't like that they provide commentary, editorialize, make propaganda or whatever your view are of it. I don't really think you get what their doing or what's at stake.
