Why were Microsoft and Discord subpoenaed over GTA VI leaks?

Take-Two, GTA VI's publisher, wrapped up its legal response to the unauthorised leaking of gameplay footage by subpoenaing Microsoft and Discord on 20 August 2026, aiming to unmask the people who distributed the copyrighted footage through those platforms [1]. It follows a wider crackdown by Rockstar, which appears to be working: the main leak channels, run through Cyberleek's website and Telegram, have since gone offline [2].
