What I read in this matches what I see in real life. Some people spend a lot of time on social media doing things that are bad for their mental health. (Comparing their lives to the ultra-filtered images they see on social media, filling their feed with information that is bad for their mental health, etc.) while others use social media to connect with an online support network.
Given that, the calls for banning social media use for kids seem odd, but they are based on that being the easy thing. Blaming big tech will never be unpopular, and there is a possibility that some people might be better off not using social media as much.
