Edit: I just noticed the list of supported countries (in my link below) includes Canada but excludes the French-speaking province of Quebec. It seems a bit spiteful to go so far as to ensure a service can be legally delivered in such a long list of countries and then exclude Quebec. Hm, I was about to use Puerto Rico as an example, but it’s not in the list as well, but perhaps it’s considered part of the United States here.
Now back to the comment I’d written at first:
It does seem to be, in typical large corporation fashion, a bit too complicated to set up. For example, there are three ways to add parental supervision, including a mode where you can transition from YouTube Kids to the full YouTube experience while still preserving those controls until a child is 13: https://support.google.com/youtubekids/answer/10495678?sjid=...
That said, all it would take is an open web browser and a not signed in YouTube account for kids to bypass these controls. But I suppose that’s not actually the point - the point of channel filtering is to reduce the harm recommendation engines and spammy content might have. The gotcha is that recommendation engines are everywhere now, spammy content is pervasive, and even AI responses in Google are arguably now a source of noise to be filtered.
I will say, however, it’s great to have an ad-free family plan for YouTube. I wish you could add more accounts to it, but for now I’m getting by with YouTube brand (sub-)accounts to create separate lists of subscriptions, histories and recommendations while still staying ad-free in apps.
And tools adults might find useful, I expect kids and teens would find useful too - for example, browser extensions to customize your YouTube experience.
As long as we have an open web for e.g. YouTube, we do have independent options, if geeky enough to pursue them. :)
An unfiltered web browser has stuff a lot worse than YouTube. That's on you if you give your kids access to that.
Unfiltered web browsers might be harder to come by these days than when I was growing up, but they still exist. I remember finding out by accident that certain restricted apps would pull up help pages, and from there I could click a link that would take me to an unrestricted web browser due to a bug in the code. I also remember computers where you could show up with pocket apps on a floppy or USB key and bring your own unrestricted web browser. On top of that, just because the web is restricted often doesn’t mean YouTube is restricted. For example, schools need YouTube to show educational content, so it often is unrestricted even when the rest of the web is restricted e.g. by dns.
