We have had multiple studies at this point and not a single one concluded that there's any kind of particular manipulation on Tik Tok. Not one. They all conclude that the bias is not different from other platforms.
HBO run a segment on the ban and goes a bit more in depth:

Content about something like Hong-Kong protests or the Tiananmen square are suppressed.
Even the data is often self contradicting.
All we see is that there's much less political discourse on TikTok than ig.
If there's manipulation, the only thing that this study shows is that the manipulation goes towards avoiding politics in general.
Not only that, but the study itself may show the reverse to be true: that IG pushes some narratives more than others.
In fact, the same result can be used to interpret as "strong traces of anti-China manipulation on American social medias".
But teaching people to ask critical questions risks unraveling the fabric of American capitalism ("Hey why is it that the government spends more on healthcare per capita than any other OECD country but with markedly worse outcomes?", "How can we call ourselves the greatest nation on Earth when we are simultaneously the wealthiest nation on the planet and still have such poor health, education and quality of life indicators?"), so we can't have that can we?
We should do that, but reforming our education system will take years or decades. And in any event, any solution that requires everyone to learn or do something or act in a particular way is doomed to fail. Humans just don't work like that.
And even with robust critical thinking skills, people are still susceptible to psychological manipulation. That's never going to change.
How long will it take to do it on a meaningful scale, all while “free-thinkers” (read Chinese and Russian bots) beat the drum of “they’re brainwashing you”?
However, that requires an education system that can be easily updated, and widely rolled out, without being shotgunned by anyone who has already lost their critical thinking ability, who may be in a position in government.
