I think people are missing the relevant facts here. It was at the urging of the intelligence and defense community that Trump "banned" TikTok. That's an executive order, not a law. It affects only governmental agencies. POTUS cannot make law by himself. (Did you guys study civics in grade school?) The app is not "banned' to the average citizen, though you'd need to be a moron to keep it on any of your devices. It is pure spyware.
I did as well as I could in high school in government class, considering that my teacher was damned near "Single White Female" like in regards of wanting to be Hilary Clinton. Anybody that wasn't absolutely brainwashed into the leftist / extreme democrat ideologies, she'd penalize their grades in every way possible. At the time, I was 17, open minded, politically neutral & looking to learn as much about each facet of government & politics as possible, but that wasn't good enough for her, so she nerfed my grades as well. In return, I saved everything from that class & had everybody else that she penalized wrongly do the same. Together we filed a class action petition with the school district against her. She was terminated & her teaching certifications were banned state wide here in Texas. We would've stopped at the city level, but figured that she'd just move over to a close neighboring city, so we took the city's results to the state board to finish what we started.
