1. The current norm of social siloing apps was created by these tech companies in the first place. What regulators can do is discourage anti-competitive practices that lock users into specific software and hardware platforms. If there's plenty of competition for every kind of social app, and competition for OSes, and users could freely choose and move between them, then not having a particular app would not result in social isolation. This affects adults as well.

2. The OS has a firewall. But it's currently not user-controllable on your phone. Phone companies have decided you don't need that feature. But actually, they can easily implement a nice UI in the settings for the firewall and lock it behind a password, then parents would be able to use it to block individual websites. We can even make it possible to import/export site lists as a txt file so that you can download/share a curated block list that you or other parents made, to block many things at once. You could also do this for your entire home WiFi network in your WiFi router's settings, if your router's firmware has that feature.

And yeah, I agree that we should make the platforms less evil in general. But I think the way to do that is to give people the ability to easily ditch bad platforms and build new ones. Let the platforms actually compete, then the best will prevail. Right now, they don't prevail because of layers and layers of anti-competitive barriers. It would take great technical effort to regulate all the tricks these tech companies use, that's why I propose dealing with it at the root: make it so that all computer/phone hardware manufacturers must open-source their device drivers and firmware, and let the user lock/unlock the bootloader and install alternative OSes. If we do this, then the entire software ecosystem will fix itself over time along with all the downstream problems.

> The kids want to use Facebook. If parent A refuses to let their kid use Facebook, then kids B, C, D, E, F... all use Facebook and kid A becomes a social outcast. This actually happens. (Well, now it's other apps; kids don't use Facebook anymore.) This is similar to the mobile-phones-in-schools problem: if a parent doesn't let their kid bring a phone to school, and all the other parents do, that creates social isolation. When the school district bans the phones, it solves the problem for everyone. (So it's a collective action problem, really.)

If so many people give their kids phones and so few don't, why ban them in the first place? Clearly the vast majority of parents are fine with their kids having one.

You're just inventing a problem then. Or worse, implement a conservative talking point.

It's possible to mandate effective parental controls and then say "it's illegal to give your child access to facebook" and then just see what happens. You don't have to jump straight to making it technologically guaranteed by construction, maybe it's enough to just give parents the tools and an excuse to say no.

We don't need DNA testing locks on cans of beer that won't let you drink from them unless you're an adult, do we? It's perfectly possible for a parent to buy their child all the beer they want, and there's nothing stopping the children from trying to peer pressure them into it, and in many countries it's not even generally illegal to let your child drink beer! And yet almost all parents are able to almost completely enforce a reasonable level of restricted access, simply because society frowns upon it.

Had this problem with my kid - social media caused serious mental health issues. Toxic content in kids areas.

But taking it away was worse.

Once “not using it” isn’t an option, government intervention becomes reasonable.
