It’s both, so what’s your point?

Valve have a lot of data on this, I’m sure 8GB is going to be substantially for most of the playable top 10

The Rust guy is saying that almost all of the 0.1% were cheaters so just removing their access by flicking a switch in EAC is a simple fix to the cheaters there.

They of course have cheaters on Windows too but that’s an ongoing problem and more complicated for them to fix.

He’s just picking low hanging fruit to address his cheater problem on Rust instead of finding a proper solution that would probably involve a way too costly rebuild of key services.

GoG also sold the modern hitman games which have DRM.

There are also many games on Steam that are DRM free, you may need to use the Steam Client to download them (but possibly also Steam CMD) but then you can copy the files off as a backup and run them without Steam
