It wasn’t even the manipulation that was the NatSec concern, it was the amount of sensitive data they were pulling of not just TikTok users but any friends or family of theirs that they had in their contacts. This means they have data on people who work in sensitive departments, military bases, etc. and they had already been established as providing that data up to the Chinese Government. It’s the same reason India banned it, it was being used as an espionage tool.

Now the other problem is that Meta will sell much of the same data to anyone who is buying. We need to do something about surveillance capitalism from private industry too.
