Valve needs to step up on Anti-Cheat (discuss.tchncs.de)

So yeah, I want to discuss or point out why I think Valve needs to fix Anti-Cheat issues. They have VAC but apparently its doing jackshit, be it Counter Strike 2 (any previous iterations) or something like Hunt: Showdown the prevalence of cheating players is non deniable. For me personally it has come to a point that I am not enjoying playing those games anymore, although they are great games by itself. But the amount of occurrences being killed or playing against cheaters is at a height, where I don't see the point anymore.

Why I think Valve is the only company able to something against cheaters?

Because they have the tools with VAC already aiming to prevent cheaters. Valve has got the resources to actually invest into something more profound which could be used for any game where anti-cheat protection needs to be implemented. And lastly Valve is the company which is interested in furthering the ability to gaming on Linux, the anti-cheat solution needs to work on both operating systems. Only Valve has the motivation and means to achieve that with their knowledge and resources. What do you guys think about the topic? Is the fight against cheaters hopeless? Do you think some other entity should provide anti-cheat protection, why? I skimmed over "anti cheat in linux kernel" posts in the net, but I have very little knowledge about the topic, what is your stance on it?

Edited: Mixed EAC with VAC. EAC seems to be part of Epic Company. Both of these tools seem unable to prevent cheating like mentioned above.

It's software I don't want running on my system and the kernel mode stuff has full hardware access.

Yes. It's a matter of knowing what you trust on your pc and understanding your threat model. Programs running in user mode can also be malicious.

Inexhaustive of things that kernel mode code can do that unprivileged (without "root") user mode cannot:

Update and install drivers.
Run programs (like cryptominers) without them appearing in the task list.
Make network requests ignoring all firewalls and monitoring tools, even when seemingly in airplane mode.
Monitor your webcam and microphone, possibly without turning on that little light next to it.
Escape any sandbox you put it in.
Replace the OS with one containing malicious code.
Replace the efi firmware with one that replaces any future OS install with the aforementioned malicious OS.
Permanently brick your graphics card.
Take advantage of buggy hardware to burn your house down.

And so on. The question you should be asking isn't "are they going to do this?" but instead "why are they even asking for this permission in the first place?".

A game where you run around pretending to be a space marine doesn't need low level access to your hardware.
