When I was on TikTok, I tried to stick to the “following” feed only, but it was very hard not to check the “for you page” (algorithmic feed), because the app is so good at knowing how to dazzle the user. It also defaulted to showing the algorithm when the app is reopened.
I only know a handful of other people who used the app, but they described the same problem: they follow people, but then they just use the algorithmic feed instead anyway.
All this to say that there are ways to present a choice to the user in such a way that users will not engage with that choice.
