EDIT: We have at least one user claiming that EAC and BattlEye can NOT see what programs are running on your computer via proton on Linux.
EDIT 2: According to brucethemoose@lemmy.world with comment https://lemmy.world/comment/24738141
"Yes and no.
If you run task manager or something in Proton? It just shows Proton processes:

But all linux process, and tons of information about them, are readable in the /proc directory. They’re just files, accessible to the program.
Try ls /proc yourself.
There’s nothing stopping anti cheat from checking that, if it’s configured to do it.
Which is pretty dang convincing to me.
If I have a good understanding, the Symlinks that Proton uses allow the games to view nearly your entire drive and see what software is running? Because Proton is explicitly NOT a virtual machine and merely a translation layer for Windows applications to run on Linux?
The reason I like to ask is because this is the general consensus, that Proton applications are not secure, but when searching online it doesn't explicitly state anywhere if the games with EAC or BattlEye are capable of spying on Linux users. So I'm looking for confirmation on this.
Symbolic links are like Windows shortcuts. You shortcut an address and it takes you there.
The problem comes in abusing both, where a shortcut takes you, and how shortcuts are assigned.
When programming for security, you never use shortcuts, as they are extremely easily to manipulate. Thus when Proton symlinks, it insecurely references files and utilities, which can allow espionage to be performed without your ability to trace it.
It's not that shortcuts are espionage, but they make espionage easier to perform.
Listen, that's cool and I agree with you 100%, but the bigger (or at least more immediate) issue here is those shortcuts being used as intended to spy on you because EAC and BattlEye are spyware.
then you have several choices:
etc.
For sure, it goes without saying that I don't play any of these spyware games unless somebody invents a reliable way around this issue.
