Every week there's another article about a new way Chinese citizens are circumventing their government's censorship. Nobody likes being kept under heel. And I seriously doubt the concentration camps would have widespread support - most likely their existence is censored from the rest of the population altogether.
They wouldn't be siding against their own government, they'd be siding against the authoritarian communist party. They'd be choosing things they really want (economic growth) in exchange for the ending of actions they either don't care about or dislike. The CP is already in a precarious balance, trying to maintain strength without turning the general population against them. Some in China already wish it would bend to the sanctions. The above kind of deal would raise the pressure on the party, weakening the tumor sitting on top of a major new contributor to the world economy.
