This episode of Last Week Tonight offers useful context for TikTok’s stunt shutdown on Sunday. John Oliver delves into the issues—including national security, privacy, and First Amendment concerns—with his trademark nuance and humor. It first aired in November but remains relevant.

(Also good: John Gruber’s piece from Sunday, which focuses on the immediate effect of the takedown, and Donald Trump’s “pinkie-swear promise” to indemnify companies like Oracle and Akamai that re-enabled TikTok in violation of the law. The fines are $5,000 per user, amounting to $850 billion for TikTok’s 170 million U.S. users. And that’s for each company in violation.)
