TikTok wants users to believe that errors blocking uploads of anti-ICE videos or direct messages mentioning Jeffrey Epstein are due to technical errors—not the platform seemingly shifting to censor content critical of Donald Trump after he hand-picked the US owners who took over the app last week.

However, experts say that TikTok users’ censorship fears are justified, whether the bugs are to blame or not.

Ioana Literat, an associate professor of technology, media, and learning at Teachers College, Columbia University, has studied TikTok’s politics since the app first shot to popularity in the US in 2018. She told Ars that “users’ fears are absolutely justified” and explained why the “bugs” explanation is “insufficient.”
