Why ban social media when ad-supported media is the culprit? Remove the incentive (to get users to doom scroll, to polarize, to impulse buy…) and you change the behavior. I remember when social media was sane 15+ years ago. The problem is the business model, not socializing. It's crazy to ban it when being a teen is the beginning of socializing!
Complaining about ads is kinda like complaining about homeless people. You are just servicing your own annoyance without actually engaging in critical thought. It is selfish behavior.
