This article is lame. No one is proposing a ban on tiktok. The law just approved by Congress only requires a change of ownership (i.e. to something other than a Chinese-government-owned entity).
TikTok would still be just like it always is, minus the pro-China algorithm/propaganda. An algorithm well known to persistently favor the views of the Chinese government (which can be very much against what most Americans believe in such as freedom of speech):
In other words, the influence of the Chinese government on teenagers and old people incessantly calling congressmen telling them to vote against that very bill. The very thing that the bill is supposed to prevent.
