As a software engineer with kids, let me tell you: not only do they already bypass parental controls on both Android and iOS (I've yet to figure out how on this one) devices, but they discover these tactics from other kids in school that were saavy enough to find tutorials online. It's not like when I was a kid and had to dive into the registry to find the key associated with the program, understand what a swap file was and why it might contain credentials, write my own code to circumvent the controls, etc. They're not really learning anything about the system when they bypass the controls.
