I don't quite understand. This reads really negatively to me, like you want to proactively judge what others privately engage in so you can "re-educate" them in case you disagree, and lack of access to that is a problem? That's a horribly authoritarian view, compared to simply broad exposure to shine light on the multiple sides of issues, to promote more informed judgment (which AI-driven content "optimization" specifically works against, as its own broader problem).

Of course, on the receiving side of info, with somebody with deep knowledge of you trying to convince you of something, again that's vigilance and exposure on your part. We all have family members in this exact role, trying to convince us all of their viewpoint, with intimate knowledge of us. What's the difference if it's a 3rd party? What if it's you promoting your ideas, and how would you want any "safety" mechanisms affecting you?
The responsibility always falls on the person receiving information, not to police other's receipt of information. The latter ends up with people arrested for googling pressure cookers.
