I honestly (no flamewar intended) wonder if the people of China (the majority of its regular citizens) suddenly decided that they're actually not happy with where the country is going, could they successfully make a change in government? Or is the power grip (+ available technology) of the powers that be (Xi and co) already too strong as to make that impossible, i.e. beyond the point of no return?

I am asking because, putting China aside, other countries seem to be headed in a similar direction if are not outright copying what China's been doing during the last years.
