From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It already works, but studios using anticheats that DO support Linux CURRENTLY don't bother implementing it because we're maaaaaybe 3% of the market on a good day, so they say "fuck it" and don't expend a few dev hours to enable it because they see it as a pain to deal with v users who need it.
AFAIK the current anticheat systems on Linux only run in userspace not at kernel level. This does mean Linux is theoretically easier to bypass compared to windows, some games just dont seem to want to take that risk. For as you said 3% of the market.
I personally disagree with that stance though, because all it takes is a hardware device and all software anticheats are useless no matter the os (think a raspberry pi, and capture card). So anticheat is really a losing battle anyways.
Yeah… Apex Legends dropped Linux support a while ago and that’s one of the reasons they cited; and tbf, there were publicly available Linux cheats that ran under proton.
But there’s also loads of publicly available “external” cheats that run the way you described. Some run through a virtual machine even. It’s just not a robust solution for preventing cheating, and mostly hurts the legit Linux players.
So true. And worse than that, we're probably also the 3% most likely to skip buying a game that requires anti-cheat, anyway. Many of us are famously un-friendly toward closed source code running with invasive permissions.
It's a lot more than just "a few dev hours". You need to invest in training your testers on Linux, potentially purchasing new hardware, invest in programmers that can deal with writing for Linux, etc... Just because something like BattlEye has a checkbox for Linux support doesn't mean that all it takes is to click the button and rebuild your game.
