Does anyone know more about the private foundation publishing this research, Safeguard Defenders? Where do they get the bulk of their funding from, and have any orgs done analysis on the quality of their reporting?
Based on my reading it seems plausibly legitimate. The precursor organisation China Action seems to have been pretty paragon, and the founder's previous work in gender equality curbs my suspicions of it being a right-wing anti-china grift.
The fact that the CCP doesn't like them is obviously true, but that could go either way for their work being factual or fabricated.
