I mean... I don't really disagree in this specific context.
I assume Fortnite has kernel level/rootkit anti-cheat. And Epic make massive amounts of cash from all the goku skins people buy. Unless they have the resources to test at least the major distros and keep aware of possible hacks/bypasses on that side it is just begging for exploits. And it is big enough that the moment one is identified EVERYBODY is grabbing an ubuntu live CD to get some goku dollars.
I still think it is shit that they don't directly support Linux with the EGS (especially since they distribute Unreal Engine and marketplace stuff via that). But for their "more revenue than the GDP of a small nation" live game? I get it.
A buddy who works on one of the popular live games made the comparison to pokemon cards. Everyone thinks it is a great idea to show them off at school. Until the kid trips, they get scattered on the floor, and it is a god damned feeding frenzy of every single kid losing their minds to scramble and fight over that dog eared pikachu card.
