I dare to say, that's from main stream media reporting?
I have wechat group where people living in mainland and abroad discussing political economic topics. We exchange information, about the most sensitive topics. Peng Shuai, covid, US politics, Xi's lifetime term, etc. We are very open, of course we do use jargons to feel safer. No one is remotely close to be harassed by rededication camp recruiters...
My friends are all very open about Western ideas. They just don't care about voting and other western values. As I said, such value system are built from very young, it takes time.
They of course admire US environment where people can speak a lot of things without risks. And I absolutely sense that they prefer the society moving into that direction.
Given 1-2 generations, I see no reason why not CCP's core members will move into a mentality that open public discussion of most sensitive issues are OK, because at the time, the core members when they grow up, already accepted such values.
Let me tell you a story. Before 1970s, people in China value the communism high vision, they absolutely have much less interests in the material enjoyment; now they can always openly pursue such pleasure without any danger. That's the change that have always been happening, and will continue to happen.
