No one did, until Raynor found that adjutant on Tarsonis in WoL. Liberty was considered a rebel to Mengsk. Remember, he was with Raynor at Tarsonis when Mengsk betrayed Kerrigan. It's just that Liberty chose to rebel in a different style than Raynor did.

This makes me wonder if the Dominion public now knows more in detail about the psi emitters. As you just said, the emitters are a secret to both sides. But if that's true, then when Raynor made the broadcast in "Media Blitz," the Dominion public wouldn't even understand what they were talking about in there. All they'd get is that Mengsk used some sort of "magical device" that somehow had the power to control Zerg, and used it to kill the Confederacy on Tarsonis.
