This is not about Europe data privacy laws. It's about businesses misusing APIs in a way not intended by Apple. MDMs are meant to allow a business to manage its devices through a third-party provider. They are NOT meant for personal usage, as they are privacy and security issues (who do you turn to when your device is bricked by your MDM?). This is not the first time Apple is shutting down businesses misuing its APIs, and it won't Apple. Should Apple provide parental control APIs? That's a separate issue. They currently don't have enough, and user who wants more can indeed switch to Android.
