Sony fined €13.5m by French antitrust regulator – Autorité de la Concurrence accused platform holder of restricting third-party PS4 controllers

TLDR: Sony would break unlicensed third party accessories connections on purpose with system updates.

That might not be so bad and well within their right you may say, but Sony also would ignore requests from these third-party companies to use licenses for their products, essentially creating a monopoly on licensed controllers.

The combination of the two things is what led to the fine as being anti-competitive and anti-consumer.

A fine is a business expense to a organization like Sony.

I had no idea they were doing this but it doesn't much surprise me. My PS4 will be my last Sony purchase because honestly the system gets progressively worse with every update. I can no longer navigate between screens or in apps without experiencing massive lag. I understand it's not supposed to last forever but the damn thing is near unusable at this point whereas my PS2 is still running.
