I would like to note that I am probably grossly unqualified to talk about such topics, but one idea that I've had rolling around is that inevitably, if you ask people "should kids be able to watch/read/be exposed to [insert adult thing here]" they will inevitably say no of course not. I feel like this is pretty reasonable. For advocates of privacy to succeed I believe that they will need to not just oppose censorship on a global scale, but provide solutions. One thing that technology has not changed is the unit of human relations. From foster care to single or two parents, the idea of a family is still there in society. In my opinion, this group is greatly underserved, and I do not believe it is enough to say "its the parents responsibility" to curate content. That is a full time job. Now, I will be the first to say that children do not at all need to have a smarphone/ipad/etc until they are in their teens, restricting all technology use can be hard. There needs to be tools that allow parents to choose what their children are allowed to be exposed to. Some parents will choose complete freedom, some will choose some "censorship." But I believe the power should rest in the hands of the parents, and I am strongly opposed to the government dictating this choice. I believe one thing the government can be good at is enforcing standards and providing reference implementations that would allow such curation to be possible. Imagine if you walk into an Apple store and say you are buying a phone for your child, and they tell you: would you like a side of censorship with that? Or if companies like youtube that are a platform with children would need to provide a means for them to be curated, for channels and features to be blocked, etc. I am not sure if what I am proposing is the right way forward but I would love to see governments tackle this problem of giving power back to the parents, instead of seeing governments attempt to enforce their worldviews onto others. I am also interested in how there would a handoff, from a "child-friendly" internet to a fully uncensored one within families. I believe that outright rejecting censorship of what children can access will do nothing to assuage the fears of people that do not want their children accessing random websites, and that a solution that keeps the power in the hands of the people and not the government is needed.
I think a practical problem with this is that even if you offer this tech you will inevitably get groups of parents insisting the government use this power enforce their values on the other parents as a matter of course. We see this already with the erosion of cultural norms for free speech.
Apple already provides heaps of tools to help moderate what children can do on the phones, you can limit apps screen times and disable some apps altogether.
People want these laws simply because its hard to say no to your kids, and it's a lot easier to tell your kids its the governments fault they can't use social media any more.
