Yeah, I'm aware of the any number of infinite Evil China (TM) hypotheticals. Let's put the sinophobia on hold for just a second, and answer my question: what are the practical (meaning documented) privacy/security concerns with TikTok? I linked to a report from a (gasp, Western) group showing that there weren't any, but I'm aware that the report is a year old, so I'm very interested in documented recent information, not just mindless anti-China ranting.
"documented". Unfortunately TikTok is closed source & proprietary. Though some privacy/security concerns can be gleaned via inspection of the binary and by viewing its network packets and such, it is still a black box running inside everyone's pocket.
