>All of this is beyond horrific.

Hot take: It's also totally unnecessary. The entire arms race is stupid.

Proper anti-cheat needs to be 0% invasive to be effective; server-side analysis plus client-side with no special privileges.

The problem is laziness, lack of creativity and greed. Most publishers want to push games out the door as fast as possible, so they treat anti-cheat as a low-budget afterthought. That usually means reaching for generic solutions that are relatively easy to implement because they try to be as turn-key as possible.

This reductionist "Oh no! We have to lock down their access to video output and raw input! Therefore, no VMs or Linux for anyone!" is idiotic. Especially when it flies in the face of Valve's prevailing trend towards Linux as a proper gaming platform.

There's so many local-only, privacy-preserving anti-cheat approaches that can be done with both software and dirt cheap hardware peripherals. Of course, if anyone ever figures that out, publishers will probably twist it towards invasive harvesting of data.

I'd love to be playing Marathon right now, but Bungie just wholesale doesn't support Linux nor VMs. Cool. That's $40 they won't get from me, multiply by about 5-10x for my friends. Add in the negative reviews that are preventing the game's Steam rating from reaching Overwhelmingly Positive and the damage to sales is significant.
