Not normally a Jacobin fan but this is pretty straightforward: the move against TikTok is a combination of anti-China hysteria, American tech companies trying to squeeze out competition, and a bipartisan attempt to censor opposing views on Gaza and other issues and politically punish young people.

Banning TikTok Is a Terrible Idea

Large numbers of both Republican and Democratic officials, including Joe Biden, are indicating their support of a measure to ban TikTok. It’s a nonsensical idea born of elite mistrust of ordinary people.

TikTok specifically and social media generally are becoming a bipartisan bogeyman for why young people are so very angry and frustrated with the political status quo and why more people are coming out as LGBT+.
