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.

I think its less a question of the technical feasibility, and more of an issue that we, as users, don't want more closed-source blobs in our kernels. Meanwhile, the publishers insist that they can't open-source their anti-cheat code; Their idea being that if we know what's in it, it will be easier to bypass.
Basically, one distro or a few(at most) may get anti-cheat integrated one day(like, say, SteamOS), but it will likely never be in your standard Linux kernal.
They could go the rought of kernel modules, I would think, but for whatever reason, we're still having this conversation.
Valve also has server side anticheat in his games (Counter Strike or Deadlock). They are also against it.
Kernel-level anticheats can be bypassed anyways, but they are the easy solution for the corps that want to sell their multiplayer game.
@MachineFab812 @SpiderUnderUrBed even if you have steamOS, what keeps you from downloading kernels from kernel.org and building?
If a person stands to make a lot of money figuring out how to use a regular, non-anticheat kernel then they will do it. It would be a lot less difficult to do when the kernel code is open source.
For anti-cheats, it isn't the case, as with Windows, where you can semi-trust that the kernel isn't lying. If an anti-cheat runs and wants to see what DMA devices are connected it uses the kernel to do that and it trusts that the kernel isn't lying. You could trivially modify the Linux kernel's source code to not list a specific card when asked by a kernel module.
Shite is still shite, even if it's open source shite.
