The propaganda really isn't anything different or special though. I've been using TikTok for years and it's no different than any other social media. You interact with what you're interested in and so you see what you want to see. Just like lemmy and reddit and whatever else. I'd argue that TikTok is a bit better for not having US corporate fingers all over it tbh.
If propaganda is valid criticism of the way our government is behaving by our own citizens on their own channels then I guess you could call it that lol. But banning TikTok is already proof that our government is full of fuckery and not working for us. They tried twice before this and the people unequivocally said NO both times. So they shoved it through in a way that makes it more difficult for anyone to hold them accountable. Because of course they did. Even people that don't like the idea of TikTok should be more like you and against this obvious power grab. They don't want to protect us. They want our data back in the US markets and our eyes back on our own homegrown propaganda that they can control. It really is outrageous if you consider it at anything more than surface level.
I don't think you know what invasive means
