I think it’s probably the 9/11 truther thing.
It’s weird because I remember Jones being moderately well-liked by the left during the George W. Bush years. Same with WikiLeaks.
Kinda like the way that for many years you couldn't see an article that mentioned "Judicial Watch" without it being tagged with "far-right", "conservative" or other similar phrases to lead the reader to believe it was nothing but a partisan hack organization. Eventually, after JW had dug into the Bush admin just as hard as they had the Clintons that it finally went away. I also recall that many of the folks cheering them on when they attacked democrats were less enthusiastic about them going after 'our' side.
