Actually, no. That's not how this works and it's not the reason behind the TikTok ban. TikTok is being banned because it's directly controlled by the Chinese government, a foreign adversary that has vested interest in controlling and manipulating the American public through propaganda.
Banning a foreign propaganda platform is not authoritarian, it's a necessary step to protect democracy from being negatively influenced, manipulated and controlled by hostile, authoritarian actors like the CCP.
