actually you do get to tailor your experience on tiktok. you can absolutely follow people. you even have the option to have the algorithm that's tailored to your liked content (fyp) or specifically look at a feed of your followed accounts.
You said that tiktok tailors every bit of what happens on the app.
I have some news for you... so does youtube and every other social media platform out there.
people who don't use tiktok seem to not really understand that 95% of the content on it is from youtube or shares creator spaces with youtube and other social media. my fyp and follows are mostly artists, musicians, funny people, animal videos and I even get some news as well.
tiktok is weirdly villanized by those that don't even use the app.
I agree with you that social media is bad, but tiktok isn't really the world ending propaganda machine it's portrayed to be. I don't know if I'd consider funny videos and anime edits to be "poisoning the minds of people".
