So then block google/YT and call it a day? It's absolutely not Google's problem.

This isn't a "real life" thing - it's not like there's a strip club with open windows next door to your house for your children to look into. We're talking about a computer/iPad/mobile phone - block YT at the DNS level or better yet, don't even give one to your kids. Problem solved.

Other people shouldn't have to be punished with breaches to their privacy because people can't manage their childs online time.
