The thing with TikTok is almost all americans on it have gravitated away from other platforms because it has more to offer. I don't think there's a large demographic on TikTok who don't precisely understand why they use TikTok over other platforms. (Edit: youth I suppose) I also believe this is why they want to force TikTok to sell, they want to have it exist as a platform but with new management.

If TikTok doesn't sell and it does get banned, I almost guarantee the demographic will quickly find themselves on another, likely Chinese owned, platform. This will still be a win for Congress as they'll have fractured TikTok and weakened the demographic as a whole.

Time will tell.
