Every generation is scared of "what the kids spend their time doing". In the 80s it was the PMRC. Later on there were at least a few video game scares ("What if my son plays Mortal Kombat and tries to rip my head off?").
I'm not advocating taking all social media from kids. Just limits and at least corporate oversight. I grew up in the 80s, with limits on my BBS and AOL time, and I survived.
Now that the Internet is cheap free and everywhere it's reasonable to ask if unfettered access and megacorps need some guardrails.
Today it's "evil Chinese apps". Embarrassing.
