alt Hacker NewsTBH, I think that wouldn't solve the core problem.
If you forced, for example, TikTok to do this right now, they would presumably add a page to their app with their recommender algorithm. Then what? Meta or other competitors might be interested in copying aspects of it, but normal users would likely ignore it and continue being addicted to TikTok.
A page on the app wouldn't cut it. Has to be on the same page. I'm tempted to say "has to fit in the button".
