Apple is once again clashing with makers of parental control apps, but this time it is reportedly being investigated by Russia’s anti-monopoly watchdog.

The investigation began after a complaint from cybersecurity company Kaspersky Lab, that the iPad maker may be abusing its dominant market position.

Apple had already clashed with the makers of a number of parental control apps back in April after it had removed or restricted at least 11 of the 17 most downloaded screen-time and parental-control apps.

Last month Apple restored a parental control app called OurPact, after the app was revised and satisfied its scrutineers.

But it seems that Apple is again rejecting those parental control apps it deems violations its terms and conditions.

According to Reuters, the Russian FAS watchdog said it was investigating why a new version of Kaspersky Lab’s Safe Kids application had been declined by Apple’s operating system, resulting in a significant loss in functionality for the parental control app.

Step forward Russia’s Federal Antimonopoly Service (FAS), which has opened an official probe of Apple — following a complaint lodged in March by security company Kaspersky Labs.

Kaspersky’s complaint to FAS followed a change in Apple’s policy towards a parental control app it offers, called Kaspersky Safe Kids.

Discussing the complaint in a blog post the security firm says Apple contacted it in 2017 to inform it that the use of configuration profiles is against App Store policy, even though the app had been on Apple’s store for nearly three years without it raising any objections.

Apple told Kaspersky to remove configuration profiles from the app — which it says would require it to remove two key features that makes it useful to parents: Namely, app control and Safari browser blocking.

It also points out that the timing of Apple’s objection followed Apple announcing its Screen Time feature, in iOS 12 — which allows iOS users to monitor the amount of time they spend using certain apps or on certain websites and set time restrictions.

Kaspersky argues Screen Time is “essentially Apple’s own app for parental control” — hence raising concerns about the potential for Apple to exert unfair market power over the store it also operates by restricting competition.
