Come on Bungie. Easy Anti-Cheat already supports Linux via Proton, and according to EAC themselves, enabling Linux support is basically a boolean toggle in the configuration. Valve fully supports EAC through Proton. Many major titles already do this successfully on Steam Deck, like Halo MCC, Dead by Daylight, Apex Legends, Elden Ring and Fall Guys. There is no technical blocker anymore — this is a developer-side decision. Steam Deck and Linux players just want official support to play Destiny 2 without workarounds or risk of bans.
