"You cannot trust anything reported out of China" "Not all things reported out of China can be trusted"
But the language you choose to use has its emotional implication. Ask any Chinese, which of the two sentences is more biased.
"You cannot trust anything reported out of China" = "Nothing reported out of China can be trusted",
while
"You cannot trust something reported out of China" = "Not all things reported out of China can be trusted"
I had a similar reaction back in 2010 when talking to a scientist from Libya (during the internal conflict). He was in real shock of what's been known for ages of his country in the west. Of course it doesn't mean everything in the western media is wrong. But he knew some facts that had simply not surfaced at all in people's view. I have a similar feeling now.
Most Uyghurs don't even speak your language. That generalization of well-connectivity doesn't apply at all. Unless you speak Äynu, you are likely talking mostly with Han Chinese in Xinjiang (or Uyghurs who had undergone severe Sinicization).
> It's almost impossible to hide any major events in China, even with large scale blockage
It is impossible to hide "major events" only when jounralists are free to roam around in China.
I have a jounralist friend whose grandfather was a Chinese war hero (i.e. he is a 红三代). He is now a US citizen, and works for a respectable news media. He had internal CCP connections but were denied Chinese visa when he was working on the Uighur story in 2017. This had never happened before, even when he was investigating the controversial story with Bo Xilai.
I don't see how the journalist story relates to this. I know exactly the kind of profile he has. Most people in/out of China know the limit of political freedom and the sensitivity changes according to political tides. It'll be quite strange that he pretends he didn't know the severity. But that's exactly my point: these events muddle the water and hide the real serious issues.
