The problem is that the pro-China position almost always comes either from an outsider (who isn’t really credible) or an insider (who is scared of giving even meek criticism or caveated opinions).

There are not really insiders willing to offer those nuanced opinions. Instead it’s up to the rest of the world to figure out what’s true and what’s not, what’s omitted, how to reconcile the two differing opinions, but without the context.

And I don’t agree that the same applies to the USSR in the modern era. I thought it was common knowledge that in post-soviet countries a lot of especially older folks held mixed opinions on the USSR (liking the safety net and sense of personal security, hating the shortages and queues, liking the international prominence, hating the corruption, etc).
