May well be nothing.
The gotcha here is not what is being said, but why it is there in the first place.
baybal2 can be quite trollish, but he gets accused of pro-China bias much more frequently. This is actually the first time where I've seen the opposite accusation.
One time, dang (who moderates the discussion here, in case you're not aware) even commented specifically to defend baybal2 and clarify that he's not a "pro-Chinese agent": https://news.ycombinator.com/item?id=21195898
Impressions based on single comment threads can be very misleading about the character of individual participants here.
E.g. if you search for articles about Uyghurs: https://duckduckgo.com/?q=uyghur+site%3Asixthtone.com There's not much wrong with those articles, except for what's missing.
Compare with the South China Morning Post, which is also sometimes accused of being propaganda, but it does cover critical topics: https://duckduckgo.com/?q=uyghur+site%3Ascmp.com
Second, he does political reporting, in fact, he specialises on it. A foreign person is simply not doing political reporting in a country like China. Absolutely inconceivable, beyond some fully choreographed potemkin village tours.
Third, what he puts in his writing, and very overt innuendos he makes from time to time feels very much like somebody doing a "write about this, and that" job. The logical, and thought flow simply doesn't feel like a news report.
From the very beginning of his articles, he already has an argument given almost like a statement of a fact, and then he steers the reader towards that with random supporting arguments. In other words, he knows, from the start, reliable facts about current events he writes about.
Fourth, where does his info comes from? A lot of things he wrote before could've only come from a first party source. How he gets access to state events to which even internal party press is not allowed?
It is 100% clear to me that he is a part of a leaking operation, and very clumsily ran at that.
