Seems like just different bubbles, actually. I'm somewhat skeptical of taking at face value the opinions of a population subject to authoritarian information controls. Even in such a case, you're likely to get very different opinions of a government like China's in Xinjiang or Tibet than you will in Beijing. Both groups are only able to form their opinions of the whole from the very limited pieces available to them.
I think the most interesting perspectives come from people with a foot in both worlds. I have friends who don't want China to become a democracy, at least not right away, because they're afraid of what it would do. The CCP has kept the necessary civil society weak, and encouraged popular nationalist sentiments that could be very dangerous if put into action.
