@allanb @MisuseCase No, you get that wrong. It's the single non-spying platform, all others are PRISM partners of the NSA.
China does spy, but mostly on their own citizens, which means Douyin users then.
Transferring ownership to an US citizen means they can send out a national security letter. The “national security issue” is that they absolutely want to spy on TikTok users, the easiest way possible.
Plus of course the surveillance capitalists want their access to the data, too.
