Just a random thought when I was playing last night: I was TEC and the insurgents I researched actually managed to bomb and take over one of the enemy planets, but when I showed up they attacked me. From the desc in the tech tree though it sounds like these are supposed to be YOUR people rebelling on your side. Is it possible for the game to track insurgents to the player who researched them and treat that player's forces as allies? IE you take over the planet for them, but they remain in their home planet instead of your being forced to destroy them.
