It's worse than that. It's a way for CCP to control minds by controlling the content they are exposed to. They use it to assign opinions and divisions to make us tear each other apart. The sheer number of "challenges" that get promoted on that app, which involve doing things that are patently and obviously self-destructive should be all the evidence we need to see it is a weapon of total war designed to kill civilians.

I think it's safe to assume that anything you see on the app, it is because the CCP believes that by you seeing it you will be weakening yourself and your nation, and empowering China.
