TikTok's leadership answers to the CCP. It is a tool for propaganda and psychological warfare against the United States. We're going to ban TikTok for the same reason China banned Facebook, IG, Google, human rights organizations' websites, etc.: as a countermeasure against psychological warfare.

It's true that banning TikTok will also benefit US social media companies. This is similar to how we restrict the manufacture of advanced weaponry to US manufacturers. Yes, this kind of policy creates an advantage for domestic producers. And yes, it also serves important national security interests. Both can be true at the same time.
