> The problem there is that parent's won't know how to do it, or won't care.

This is unfortunately the reality.

The other day a friend asked me to help her make her phone safer for her kids to use. I started by asking if she set permissions on the apps she downloaded. She looked at me blankly, "What permissions?". I proceeded to show her how you can granularly control what you allow each app to do on your phone and what access it is allowed. Her head blew up, she had no idea any of this existed and after gong through a few menus, she didn't care any more. It was all too complicated and too much to think about for a busy mum.

This is why governments unfortunately are having to try to protect people from themselves. As tech competent people it all seems so simple to us, but we need to remember the majority of the population just click 'Allow All' and blow past all permission and security questions as they have no idea what any of it means.

UK mobile operators already defaulted to blocking adult sites before OSA, and lets the subscriber turn it off, which seems like a reasonable option.

It'd be even better if there was a way for people to selectively turn it off for specific devices without MITM the connections. It wouldn't be that hard to come up with a mechanism for that.

When we buy a new phone, the configuration process should ask if the device will be used by a kid. Easy and simple.

When restoring factory defaults, the same question, just in case the phone is sold, gifted, stolen or whatever.

If you are going to give a phone to a minor you should set that option right from the start.

That's why the setting should be on the device, not the browser or individual apps. One setting that you could even get pre-configured when you buy the phone.

It's ok if parents won't care. It's a choice too.

I've build some moderately sophisticated server systems up on "bare metal" (as the kids say), know my way around a shell better than most programmers, understand networking better than most programmers, et c., and I still find restricting and monitoring kids' devices to be a huge pain in the ass. The only places it's not extremely shitty are the Switch (which still isn't great) and Apple devices.

Options between "we don't have tech in the house" and "wide-open tech, we have it all" are all some amount of painful, usually for no good reason.

(I remember once investigating how to do some pretty basic stuff for this in Linux, hoping to find something nicer than manually setting some executable permissions and firewall rules and then having to go back and change them all the time, and the closest thing to a guide I found was an old article from Red Hat that basically lead with "LOL, good luck you poor sap, Linux sucks at this" before going on to explain the various bad ways available to sort-of, but not entirely, accomplish it with a lot of work, and significant ongoing time-burden)

That’s not true. Every TV app has a parent setting. That’s really easy to use browser support profiles just like TV apps do bad. UX doesn’t mean that it can’t be set up easily for parents. Windows itself could have profiles for kids that has all this set automatically. It’s not hard. There’s just no will to do it.

if parents wont make the slightest bit of effort why should the rest of us pay to keep their children safe?

A child can still access knives if the parents don't care.
