What are your objections exactly? He always comes across as even handed on most of his posts. Not to mention whatever you feel about him doesn't invalidate what he wrote. Even in the comments people from moderate Sinophiles like Ralph Litzinger to the hardcore pro-China nationalist like Cyrus Janssen seem to be in agreement.
Fundamentally, he does not view things in terms of geopolitical competition or contemporary technological competition, and tends to draw false equivalencies, and also he tends to minimize or disagree with the CPC in terms of what are key strategic goals and priorities of the state.
Furthermore, in this specific case, reliance on anecdotes and his own personal encounters (which in turn depends on his own degree of selection bias) are the flaws. That isn't to say personal anecdote is useless, and I think we can pretty reasonably say that there are domains of the Chinese economy and society that have varying degrees of pessimism, but posting him as if he is one of the "best China commentator on twitter" is amusing.
Describing him as "not the worst Chinese shitlib type on Twitter" perhaps is more accurate.
