“shits on Linux gamers”, are you talking about the store not beeing available on linux? Meh already got heroic which is better.
Their easy anticheat is available through proton tho, it’s on the game dev to chose to enable it or not (and I understand why they don’t do it for fortnite : the Linux market is pretty small, but also because the game is so huge that hackers will not hesitate a bit to switch to Linux in order to hack with custom kernels).
