I didn't notice the tone, but there must be some of it. I think the author tried their best to sound neutral but if they strongly believe what they believed it, it's unavoidable for letting personal opinion slip in. I once asked one of the author - nerdhaspower, to remove such words as "中共" from his site because they show confirmation bias. He refused. But in this paper, they did a much better job.

I don't believe the paper implied what you said. The first reference for example, also a well-written paper, is from a Harvard researcher, who has nothing to do with the organization.
