Reading the article it isn’t a problem with tech.
Yet again it’s adult’s inability, ignorance, or unwillingness to limit access to sites and place time limits on devices. Parents don’t parent, parents don’t want to deal with taking devices away, people can’t seem to manage parental controls or learn how they work on the device or the home LAN.
It’s not the tech’s fault. It’s the adult’s fault for not adulting.
(As a side note, people on lemmy need to remember that this is the “average” user, so when you suggest some stance on tech, this is the world outside of the fediverse where people can barely manage an iphone)
