And pointing out anything that has nothing to do with Tiktok in a thread about Tiktok is not providing context, it's an attempt at distraction and deflection away from the thing you trust (the CCP, somehow) towards the thing you don't (the US Gov).

"I just can't believe that a powerful country like America is letting a not-so-friendly military/civilian complex infiltrate it for somewhat unknown purpose."
Are you for real? The one country that fits the description of not-so-friendly military-complex is the U.S. itself.
A more pressing problem and question is that despite everything we learned from the CIA and NSA leaks, American companies and their software is inside every country, government, business and IT infrastructure, and is collecting vast amounts of sensitive data still to this day.
All while people like you are drawing attention to TikTok.
