Go travel to lower tier cities and rural places in China. The development those places have gotten in the past decade are huge. Go talk to regular people ask them to compare 10 years ago with now.
You can travel to Xinjiang and witness for yourself whether religious people and minorities live in daily fear of concentration camps and organ harvesting. There are no special travel restrictions beyond standard country-wide visa requirements. If you're in a western country then odds are you can enter visa-free.
Go to Russia and ask the average person on the street what they think of Putin. Thing is, the people who had to be afraid are already long gone. The rest just didn't care or tried to stay safe rather than prioritizing their beliefs and principles.
You really think the people who are left on the streets feel free to speak their minds if it would conflict with what the Politburo is enforcing?
I'm not asking you to hear what they say, I'm asking you feel their fear (or lack thereof). If all the allegations are true then they don't need to say anything, you can feel the fear effortlessly, there's no hiding that. Also, nobody is stopping you from interacting with them in a place without cameras and witnesses.
Also, China has got nearly nothing in common with Russia. Don't lazily lump them together just because western popular thought likes to put the same label on them.
I mean, catholic priests do get taken every year in china by the government. Outside reporters do have very significant evidence of organ harvesting. You can say that you wont feel fear from the people in china, but that doesn't really change the truth.
