The CPC has TikTok data, and the US (through PRISM) has iCloud, Microsoft, GSuite, Facebook, and now likely Snapchat too. Separately to PRISM, the NSA intercepts data at the backbone level, which is for example how they could get every last byte of data Google has by tapping the network links between Google's datacenters (the "MUSCULAR" program). The "search warrants" are rubber stamps. The NSA's MARINA program collects metadata on everyone in order to do "patterns of life" analysis; this explicitly includes U.S. citizens because "metadata is not considered data" by section 702 of the FISA Amendment Act. The U.S. has also been documented to have infiltrated various peace groups/activist groups. Is the U.S. government a national security threat?
These are all privacy issues, but they're not national security issues. What's the exact concern here? TikTok being able to create voice and faceprints of US citizens? So can Snapchat or FB Messenger; and I would hope no CIA spy (the only people the CPC would actually care about) has a TikTok account.
What else? The CPC using TikTok to push pro-China or pro-Russia propaganda? Pro-Russia content was banned from TikTok, and TikTok isn't known for its popular pro-China videos. Promoting pro-Trump "propaganda" to "subvert" the U.S.? Trump is banned from TikTok. Where's the "subversion"?
