Satellite phones are out of reach like meth and online political dissent is for the Chinese, yet still everywhere.
Regardless of mispricing in your links for the average mainlander (they make most satphones/data receivers) hundreds of millions of people in China could still afford it at the prices quoted.
This isn't some small Finnish town we're talking about, it's 1/5th of every person alive on Earth.
Maybe (I would be more comfortable with a claim that tens of millions can afford them), but they don't have them. Why not? Because the affluent "elite" largely consists of the CCP's 91 million members. They are the winners in the current system, and therefore the least likely to oppose it.
What China fears and cracks down on is free flow of information to and between the masses of ordinary Chinese.

Moving the goalpost there. 1/5 of Earth's 7.8 billion is 1.6 billion, not your "hundreds of millions".
