This is utah though, a state mostly controlled by mormons. The mormon families I know take all their kids’ electronics before they are to go to bed, and don’t give them back until the morning, some incl 18yo in high school. Monitoring everything they look at to make sure they don’t see anything that could make them question their beliefs is common
This is just them pushing the strict control all the hyper religious families in utah already exercise onto everyone else, like all the other silly laws in utah
