Because the monkey in the White House says so... I’ve asked multiple times in other threads and no one was able to provide forensic evidence. The reality is, it isn’t. They collect data, similar to what Facebook, Google and others do. I’ve posted in another thread what data TikTok is collecting. Difference is, no access for the US and that’s why they want it gone. And after all, it’s China, so it must be evil...
LinkedIn collects and sells very sensitive personal info. No one bats an eye because the NSA can do surveillance on that company's data.
But TikTok, well you better be careful about all that sensitive info. LOL.
