It continually amazes me how little effort people make in Western online discussions to put themselves in the shoes of someone who's seen their country go from utter poverty to relative wealth in one generation. That person might want to gain more political freedoms eventually, but they mainly don't want to destroy everything by plunging the country into chaos.
Keep in mind that the catastrophic experience of the Cultural Revolution soured many Chinese people to politics, and convinced them that stability and steady improvement of living standards are the most important things. Many people who remember those times are allergic to any sort of fanaticism.
Also keep in mind that although many things are restricted in China, the country has opened up a huge amount. In contrast to how things were not so long ago, Chinese people are now able to travel around the world, and largely live their lives without experiencing much government interference. The limits on political activism are clear, but most people just focus on improving their own situation and enjoying the modest luxuries they can now finally afford.
It’s often inconceivable for them to understand because their life experiences are just so different. Ask anyone from a poor nation about China, and while they may dislike the government, they also talk with admiration at how many people were lifted out of poverty.
