The fiasco leaves one big question: will TikTok stay for good? Why it matters: TikTok’s return to operation after its ban, though brief, raises larger questions about its future in the US. The app began operating again on Monday, but TikTok was still unavailable for download in the Apple and Google app stores. When announcing plans to sign an order to save TikTok, Trump demanded that the US hold 50% ownership. Context: The TikTok ban debate in the US stems from national security concerns, driven by allegations that the app could potentially allow the Chinese government to access US user data.
