I think this is why it is important for western countries to encourage immigration from Hong Kong and other parts of China. Right now a lot of people feel like they can't speak out because it may affect their future or their family's future. But if they can see a future for themselves where they can build a good life outside the reach of the party, then i think they might feel more empowered to be critical of it. And criticism from ordinary people in the diaspora is surely going to reach the domestic 老百姓 more effectively than anything foreign allies might say.
