Let’s run a thought experiment:

All videos get assigned a 0-1 anti- vs pro-CCP score. Videos with a >0.5 score get a slightly (~5%) better chance of being shown, and <0.5 is slightly penalized. This would be undetectable if the algorithm is run off device. Anti-CCP content would still play often. But on the massive scale TikTok runs, this would still tilt opinion favorably towards CCP.
