The wealth possessed by the 3I's Nobility is
vast. Far greater than anything a measly little rebellion could mount. This means that anti-rebel forces are going to be well-equipped, well-paid, and well-trained. Coordination and communications amongst anti-rebel forces will be extensive. Their morale will be high, and they'll feel they're working for the right side (or, at least, the winning side) against stupid morons.
The existence of the NAS tends to put a quick damper on low-tech guerilla warfare. It would take high-tech jamming to stop an NAS, I think (or some pretty snazzy high-tech headgear), which removes "low-tech" from the equation); and EM emissions are their own problem.
The rebels will need to infiltrate the ranks of the Nobility's servants, in all areas, from the ground-up, in the civil and military branches. Infiltrating the intelligence services will be a lot tougher. TL-15 Psychological Sciences will be able to determine a lot that we can't today, and do it more reliably. Plus, TL-15 technology will provide plenty of systems that make a TL-7 or 8 lie-detector look like a Dick Tracy decoder ring out of cereal box. Advanced psychology and technology will combine to assure a high level of reliable entrants into the intelligence services, and a low level of disgruntled employees and employee sabotage (both passive and aggressive).
Overall, I think the rebel's would not be able to carry out an action, Imperium-wide, that would be successful. Maybe a few worlds, yes. Maybe. But then the IN shows up and bombards them back into the stone age (which the IN has done before, historically speaking).
Only an actual take over of large fractions of the IN would really allow the rebellion to succeed. IMTU, there are plenty of anti-rebellion safeguards on the IN to prevent a recurrence of the Civil War.
The rebels would be working against an array of forces layered into place over centuries. Their only advantages would be fitting in between the cracks . . . like a stainless lanthanum rat (maybe).
