Both sides really do have mass surveillance, China's being a bit further along and a bit more omniscient.
I don't think TikTok, a collection of six-second clips of teens messing around represents a real, material, meaningful threat to freedom and democracy. Even if they collected all the footage and ran it all through their national security apparatus. The signal to noise ratio on this content is incomprehensibly low.
This is grandstanding and showmanship on the part of two strongmen leaders, one totalitarian overlord and one wannabe, and really, I don't think there's a clear right side and wrong side here.
I guess this is where we agree to disagree. I do think a foreign power with direct and absolute editorial control over the #1 content delivery network of an entire generation of our population is cause for concern.
I'm not discounting your skepticism that there is grandstanding involved, but from your comment I see a dramatic difference between a wanna-be totalitarian in a free democracy and an unequivocal one in a single party state. Let's not let perfect be the enemy of better; while domestic surveillance is unacceptable it is most definitely better than the current situation.
I don't love the NSA, or Trump, or the US military-industrial complex, but parroting this "both sides" garbage just makes you sound like a useful idiot for the CCP.
