We already have a version of the child phone: it's parental supervision.

When I was a kid there was no TV in my bedroom nor a computer. Everything I watched or did online was on full display in the family room. What changed in the modern home where that's not the case? Are kids glued to their phones because their parents are too?

I completely agree. In fact the tools already exist to make a “child” phone. I was just giving up some inconsequential ground since many people are apparently stuck on the government padding the earth to protect their fuck-trophy. “OK - government mandated OPTIONAL DNS filtering on all routers. Super easy interface, auto-subscribe to government compiled list.” Scratches their itch and doesn’t affect me since I just won’t enable it, nor will I buy the “child phone”, and I don’t have to send a rectal scan to Facebook either. Yay all around.
