Sony has been fined €13.5 million by French antitrust regulator Autorité de la Concurrence, which has accused the company of "abusing its dominant position in the market" by restricting third-party PlayStation 4 controllers.
Filed by the regulator last month following a referral from French controller manufacturer Subsonic, its investigation found that Sony put counterfeiting measures in place in November 2015 that caused third-party controllers to regularly disconnect from the console during system updates.
The competition regulator also found that third-party manufacturers faced difficulty in joining its licensing program, which it alleged that Sony "refused to communicate" terms and criteria to manufacturers who'd requested it.
