Runkevicius complains that Apple removed parental control apps from the App Store after it published Screen Time. This is true, but Apple doesn’t make any money off of Screen Time.

Because iOS lacked bound control points out of the box, the only way to enforce them was via provisioning profiles, which were designed for groups giving gadgets to personnel. Installing a provisioning profile gives the issuer a serious amount of handle and perception into the activities of the user.
