it does help. i think this is a good step in the right direction.

but there's still a lot of stuff that only parents can do. for example, screentime in the home. you can't really create a law that says no screens for anyone under the age of X because there will exceptions (movie night, homework, etc).

Screentime helps, but it doesn't really solve the problem. They still see the exact same content shared by friends at school, and 15 minutes a day is enough to do damage.
