TikTok ban: all the news on the app’s shutdown and return in the US

Here is a 202-word summary of the key points from the news article: The TikTok app in the US faced a potential ban in 2022-2023 due to national security concerns over its Chinese ownership. After negotiations, a deal was reached for a US-based joint venture involving Oracle, Silver Lake, and MGX to oversee TikTok's data protection, security, and content moderation for US users. The ban was delayed multiple times as the deal was negotiated, with President Trump and later President Biden involved. Lawmakers from both parties pushed for a nationwide TikTok ban, citing risks of data harvesting and censorship by the Chinese government. However, TikTok challenged the ban in court, arguing it violated free speech rights. Ultimately, the deal was finalized in December 2022, with the joint venture set to take over TikTok's US operations by January 2026. In the meantime, TikTok made efforts to increase transparency, open a US data center, and emphasize its independence from China. The app remained available in the US throughout the ordeal, though it was briefly removed from app stores at one point. The saga underscores the geopolitical tensions and data privacy concerns surrounding Chinese tech companies operating in the US market.
