1. tiktok is banned in china. Potential product safety angle of 'don't ship us things that aren't legal where they're made'. (But would presumably need new regs here).
2. trade policy -- western social media is banned in china, let's at least not allow theirs to sell stuff here? Article says 'tiktok has not monetized so no point in banning transactions', I think they're oversimplifying the impact of saying 'no income at all'
3. stronger privacy laws generally -- rules about where data is domiciled (or at least honestly disclosing it), how it is used, real audits, and real penalties for violators. (this should apply to domestic cos too)
4. WTO subsidies / anti-dumping? But this probably applies to many tech companies + could escalate badly. Also not sure if tiktok is gov-subsidized -- I think an SOE has a minority stake
5. 'kicking them from app stores would have no impact bc of existing install base' feels naive
