“Any online platform and/or application that delivers content to users may deliver only content explicitly requested by said users.”
That’s it. No algorithms, no autoplay, no “You may also like,” no “Up next.” Only what human beings (AKA “consumers”) choose. Now you don’t have to ban TikTok, and you will reduce the power that Facebook, Twitter, and all the other social-media platforms have over the minds and emotions of their users. It will even reduce, though not eliminate, the ability of Spotify and other streaming platforms to ruin music.
(I’m sure many other people have made this suggestion.)
