My Daughter reasonably regularly sends through tic toc clips that can be quite funny, or just simply interesting.
I would prefer if she would not view that platform at all but suggesting that to a 29 year old is fruitless. Yet it can be good for a few laughs. She's smart educated and I just see no reason why she would subject herself to all the other rubbish on there. The issue as I see it is the myriad of garbage that simply is not healthy for anyone to be exposed to, casually or otherwise, and that seems to be the majority of it.
It concerns me that while she spots a gem or two, she is exposed to a world of absolute trash just by nature of how tic toc works. And that goes for every other child, kid, young adult, out there. Adults are who they are at that stage of life, so if they enjoy the garbage on there, no ban will protect them. Stopping the young however that can be done should be the priority and if that means banning the app, so be it.
The Chinese aspect is a whole other matter, and in my view a big one, whether US related or any allied nation as we are. I have very firm views and concerns about China, none of them positive.
For me, this world we live in now has crossed too many red lines, pushed too many boundaries, and damaged too many youngn's with stress, anxiety, suicide, feeling like they have to keep up with the other (who in many cases are damaged goods themselves), and has in simple terms deteriorated significantly over the past 50 years. Technology ?
Allowing applications like this, and other unfettered platforms to exist, continues to unravel society and morals that youngn's need in order to grow up with a healthy mind (not talking about religion etc, just positively focused), to prosper career wise, health wise, and as caring individual.
