> This is because software engineers never actually use devices that have parental controls enabled Well, I do. Back when I was ~13 years-old I tried to block one of my parent from visiting gambling sites with the parental control feature in Internet Explorer ~6 so they can't download virus, and I do have Software Engineer in my job title. Unless of course by "software engineers" you specifically mean the period of life after one been granted with that title, then in that case you won. Of course, my parental control efforts never worked. As many security researchers has suggested in many different ways, it is hard to deploy security if the attacker can touch the hardware. One's parent can just pay someone to reinstall the OS, removing every trace of your security measures along with all the projects that you've saved on that computer. In addition to that, the parent could also administer a reasonable dose of beating enough to convince you to not deploy any similar measures on the newly installed pirated OS ever again, and given the fact that the OS is already preloaded with adware and viruses, there is no point of doing that anyways, so you give up with them.
