Like the other user said, this is clearly a problem if you allow any platform to exist. Let’s take this to an extreme extent. Say a company invents a platform that is 100% addicting, because they’ve figured out how to mind control you. Watching a single video means you will never stop using the platform and you will say whatever the creators want. Clearly that shouldn’t be allowed to exist. Things that social media sites do approximate that. They manipulate users brains into doing things that they normally wouldn’t do. This is why regulation exists. Clearly my example is farcical, but it’s meant to explain why you don’t allow just anything to exist. As a society, certain things are more dangerous than others, and we regulate those things.

Clearly this ban isn’t about that, it’s about a Chinese government doing something that the US government only wants US companies to be able to do.
