Are you going to have a go at C++ then for compiling the game in the first place? Ooo let's have a yell at assembly for running the game too. Maybe Intel or AMD could cop some shit for performing the instructions, Nvidia as well just to be sure.

I'm not the other person, if it's conflicting then idk what to tell you. I work in security, but I'm not the biggest expert on proton. I know enough to understand it's not an emulator, it's a compatibility layer, and that means it runs the code that was written to the best of it's ability, on your hardware. Happens to run as you. You're having a go at the environment, i.e. the packages and software that makes the game run, for the actions you and the game developers made. Don't run spyware if you don't like spyware, or run it elsewhere.

Can the games scan your drive where your user can navigate? Yes, they have to. Can they see other programs that are running? Yes, they have to. Can they read, edit and make changes? Yes, they have to. Can they capture input in other software? Not unless you're on Xorg, then probably. Can they make web requests and send your data outside the machine? Yes, obviously they have to.

Congrats, it's spyware if it wants to be.
