Anyone remember when they were in school and adults tried to ban access to a popular website? I imagine this ban will go down exactly the same. Never underestimate a bored teenager's ability to bypass tech restrictions. Heck maybe this is what is needed to finally get a new generation out of the comforts of their tech walled garden and get their hands dirty.
This ban does nothing about the mobile tick tok website. You don’t need to be a techie to use the browser on your cellphone. Yet it is a point of friction compared to an app with native notifications. And given the expectations of the average american tech user who has been coddled for the last decade into safe app store apps instead of the scary web, people are legitimately concerned.
In any case, yeah, I'm not sure that "the average american tech user who has been coddled for the last decade" knows what a web browser is. I've observed some user behavior among family members that indicates a pretty bizarre mental model of how the Internet, web, and mobile applications work.
