US Solicitor General Elizabeth Prelogar takes on the question of how (hypothetical) TikTok “covert” data manipulation by China poses a uniquely pressing threat, but Justice Kagan seems skeptical. “Everybody now knows that China’s behind it,” notes Kagan — so is any shaping of the algorithm really covert? She points out that you could make a similar argument about manipulation for almost any social network. “You can take any of these algorithms ... none of these are apparent. You get what you get and you think, that’s puzzling!”
