Except they can't choose for their kids, or at least, not easily. Google basically own the android ecosystem and they don't want to provide any controls that could be used to limit their ability to generate as revenue. Look at Chrome's extensions. Try blocking domains. Your only hope is to use the god-awful Google Family controls AND NextDNS AND an adblocking mobile browser. These days some parents are trying to get schools to ban phones, because individual parents can't, "or my little Tommy will be the only one without a phone". So you then have to worry about what other kids have access to. Porn in private WhatsApp channels etc.

The biggest problem with giving kids phones is that it opens them up to potential non stop bullying over WhatsApp/iMessage/etc. And yet the online safety act doesn't even claim to try to "do something" about that (not that it would be possible anyway but that didn't stop them elsewhere).

As a parent who using family link, I don't find it bad or inadequate. What is bad about it. How is it unfit for purpose? My child literally has no access to anything I don't want her to. If I had a complaint, it's that tracking her media consumption on YouTube is a PITA.

The whole "my kid will be left out" thing is so bizarre to me. So what? My kid is already banned from Roblox and that means of her whole circle, she's the only one who doesn't play and oh well. When I was a child it wasn't uncommon for a child to be without something their peer group had usually for money reasons. I don't see technology as any different. Kid has stuff their friends don't and vice versa.

That's why I get mad about age restriction laws on the internet. I do want to introduce my child to some of these things in a supervised way so I can teach her about them. Something I can't do if it's literally illegal because other parents decided to shove a phone/tablet in their kid's face and walk away.

I know way too many parents who never bother to use parental controls and learn that they're not actually will to live through their kid's whining about their restrictions.
