This is really a slippery slope and I have mixed feelings about it.
I don't necessarily believe that TikTok is a good thing and while most of the videos are innocuous, it's not those videos that can potentially be dangerous. It is the back doors that allow China to gather intelligence by accessing confidential information on phones, including microphone, camera, email, location, etc. I have told both of my children that putting the app on their phone is probably not a good thing. I know that they look at videos but have no idea if the app is on their phones. I am not a helicopter parent so I really have no idea if they followed my advice or not and I really can't enforce my recommendation. I know parents that will tell their kids that as long as they are paying the phone bill that they have to have full access to their phones and they have to share their location at all times. I refuse to go there with my kids.
While it is not documented that China actually uses TikTok to gather intelligence and spy, they are not to be trusted. Also, China should be hurt economically whenever possible. I always look at products and try not to buy Chinese made products, but it really is impossible not to buy anything made in China. Not using TikTok is one thing that can be done.
The opposing view of all of this, and the Reagan Republicans, will be opposed to this. The slippery slope becomes protection of the Constitution. Where do you draw the line? Will it soon lead to what we can see and watch, how we raise and educate our children, how we dress and what we do with our own bodies? Some of that is rhetorical because it is already happening. Reagan is probably rolling in his grave at some of what is being done and/or proposed.This really should be a bipartisan thing and not become political. Biden has already banned TikTok from government devices. Ultimately, this is probably not something that is going to be hashed out at the state level. And additionally, there really is no way for Montana to enforce this or they become like the helicopter parent and that is a bad thing.
