You mean critical of the government. They also been critical of the UK, US, and Korean governments. Not to mention why they are most critical of isn’t the traditional reasons, but by the fact they need to ramp up social spending but hasn’t
Also it seems they are cynical of the numbers coming out, which is a fair point considering the Chinese researchers has a history of overcounting, inflating numbers, and sugarcoating CCP policies
At worse you can say they are anti CCP like other western sources like you said, but at best they just critical of any government who doesn’t increase social spending
