So, TikTok was 'weaponized' to be harmful for certain countries and for select age groups? In what way?

YT Shorts and FB Reels exist because they copied the TikTok social graph and business model, which makes them also harmful but not intentionally since they're just copies?

Seems to me that TikTok, Shorts and Reels are all just mirrors to how stupid and banal most people are at any age. If we ban TikTok we should ban all of them, and I have no problem with that.
