Facebook knows your education, where you went, what class you were in, what friends you had at that point, how you look, how you looked 10 years ago, what family members you have, what relationships you have and had, where you work, what establishments you've recently visited, what articles you engaged with more than others on your feed. And a lot of it isn't even voluntary because other people can fill it in for you.

TikTok knows my age, my location and viewing habits, TikTok knows that I stared at clip x more than clip y. TikTok might have figured out my age, gender and my sexuality based on what I watch and can probably figure out more just from what I view but saying it's somehow more than Facebook is inane.

one is literally made to have as much information about you as possible, that's like the core concept of Facebook.
