What would help so much would be to force the platform to act in a way to not try to retain the user at every cost.

Like YouTube. I would love to have parental settings, "no shorts", "no recommendations on video page". Kids could search and click on the creator to see more. Combine that with blocklists and curated allow lists. Boom, YouTube is not a problem. And kids getting bored of clicking around would be a feature.
