When there's a thing that's popular, but demonstrably bad...how do you get rid of it?
Alcohol, (specifically alcohol abuse) is bad for the individual and for the community. Because of the latter, it's not a 'personal preference' thing anymore. So, they attempted to regulate it by enforcing a ban.
TikTok is exactly the same. There's nothing wrong with a video posting service. There is something wrong when people are being harmed by that service (ie, dangerous viral challenges, misinformation, spying?) So they are attempting to regulate by enforcing a ban.
However, because of its popularity (whether earned or addicted) the users say NO! And either reject or ignore the harm, and just say they want it anyway so they get it in another form, or from another source.
If you have a responsibility to protect the community what do you do?
