>Surely Facebook’s a bigger issue than 60 second videos since any bad actor can target messaging at susceptibile users and no one will know.

TikTok relies much more heavily on an algorithm than FB, though. FB primarily pushes content posted by your friends, while TikTok pushes anything that might interest you. They can subtly influence you. If they hate Trump, the can push joke videos about tax returns and his sexual assault allegations or something. In other words, try creating an unconscious association between Trump and evil in your brain.

Another issue is that, if TikTok becomes crucial for advertisers, we give China power over these companies. Hiring people who have publicly expressed anti-chinese opinions or donating to the wrong politicians might suddenly ban you from the platform.
