That's a great idea. The only issue I see with it is that eero doesn't have the resources to do something like this by themselves. It's a lot of work to keep track of sites, categories, etc and would require a dedicated team. Their current parental controls in eero Plus uses a partner, and they'd have to find a partner that does parental controls better than Circle. Unless you know of a partner that already has better functionality than Circle, the more obvious solution would be to simply partner with Circle as Netgear has. All IMO, of course. If eero can do it on their own, that would be fantastic!
