I can believe that there may be a policy to push educational material to kids but that doesn't contradict with the claim that such content doesn't drive traffic. So the initial claim about what's actually viewed on Douyin is way off the mark.
I still don't follow. You accept that content on Douyin is controlled, but not to the degree that's being reported? And that censorship is absolute, but the engineering of all content flows based on age doesn't exist ?
No I am saying that all that engineering could reveal human desire but not necessarily change it. They could push educational content to children but that doesn't mean children would take it. Also it is well known Douyin's focus and success lies in live streaming e-commerce.
