Here's some new perspective from Apple itself about these security problems, responding to a public relations issue:Not at all, Robbie, the only thing I'm "suggesting" by posting information about a dangerous attack vector is that people should be wary and aware of it, so that they aren't losing valuable / private / personal / sensitive data to criminals or others without realizing it through this sort of trick.
Apple PR said:The facts about parental control apps
Over the last year, we became aware that several of these parental control apps were using a highly invasive technology called Mobile Device Management, or MDM. MDM gives a third party control and access over a device and its most sensitive information including user location, app use, email accounts, camera permissions, and browsing history. We started exploring this use of MDM by non-enterprise developers back in early 2017 and updated our guidelines based on that work in mid-2017.
MDM does have legitimate uses. Businesses will sometimes install MDM on enterprise devices to keep better control over proprietary data and hardware. But it is incredibly risky—and a clear violation of App Store policies—for a private, consumer-focused app business to install MDM control over a customer’s device. Beyond the control that the app itself can exert over the user's device, research has shown that MDM profiles could be used by hackers to gain access for malicious purposes.
