Why does tiktok do this? I find it so weird.

I think its so weird that tiktok is trying so hard to let us take pictures of ourselves to join the "let tiktok decide the music it will put in the picture" so many different types of videos saying "It's so accurate" "Omg i can't believe tiktok knows me so well". It does this all the time. It's like an ad. it feels like a virus. Another example was the search, your name and the outfit trend, or search your zodiac sign and your outfit.

Why does tiktok do that? Want you to use the search bar or use the camera so badly? It's weird. Another time I realized it changed the perspective; gave me a "spiritual" video saying tiktok checks the vibes through the camera depending on the sound of it, it reads your energy, to see if it's off or what. Or even "search these three words up" thing. Why does it do this? It's honestly creepy asf.
