I don’t know who specifically you mean by “local oligarchs and warlords”. Do I think TikTok has more power and influence in the US than the average Fortune 500 CEO? Without a doubt.
Why do you bring up "Fortune 500" CEO:s? They only administrate businesses, they don't own them, unlike oligarchs.
When you read that quote, you can't think of anyone that would fit? You don't come to think of the Kochs, Clintons, Trumps, Musks, Obamas, Sacklers, Murdochs, Bidens and so on?
No, and even with those names listed out I don't really understand what category you're pointing at. Your list includes the sitting president and president-elect of the country, who do of course have quite a lot of power. Do I think that TikTok has more power than Rupert Murdoch? Probably not, Murdoch owns a wider variety of media even if he doesn't have any single dominant app. More power than Richard Sackler or Bill Clinton? Again, yes, without a doubt.
As a myth- and truth-maker I'm sure Bill Clinton outweighs TikTok by a huge margin. Compare speaking out against his recent theocratic and genocidal outbursts with speaking out against some stuff on TikTok, one can get you fired from middle class positions of authority, like teaching at universities, the other is perfectly safe unless it also goes against US elites.
I don't know what "theocratic and genocidal outbursts" you're referring to, but it's completely untrue that criticizing Bill Clinton can get you fired from teaching at a university. I'm not sure where you could have gotten the idea that it's rare or dangerous to criticize politicians in the US.
You should listen to his campaign speech in Dearborn, and later he went to a conference and basically said that the palestinians deserve to be exterminated because Arafat left the Camp David talks.
Over the last year many US academics and students have been abused because they openly dissent with or protest against the warlords in charge.
