My stance is this, most of the big names coming out for a ban are either conservative leaning institutions or just plain conservative. FBI and Marco Rubio. (I'm old enough to remember a rogue FBI branch pressuring the FBI director to release a scathing report on Hilary Clinton just before the election)
I think TikTok is filling a void for Democrat messaging that Republicans/Conservatives have ie: Fox, conservative youtubers, breitbart, etc. The left is doesn't have this and TikTok has been useful for sharing concise information in a repetitive and engaging fashion. I have a hunch it's a large reason why we had such big youth turnout this midterm election cycle.
TL;DR: Ban TikTok when there's a good home grown replacement. Or Nationalize it's US/Western wing and spin it off as a separate entity
