Are you saying MK ULTRA is just a conspiracy theory and never happened? I’ve watched documentaries on PBS, BBC and the History Channel. Clearly the program existed, as for what clandestine operations it ran, that’s certainly loaded with conspiracy theories.

If everything is a conspiracy theory, nothing is a conspiracy theory.

From what i understand any changes to the system outside of the userland will be overwritten after a SteamOS update.

Hmm, I wonder if SteamOS has AppArmor by default so I can tinker with it.

Thanks for the suggestion, I think the main issue is doing it on the Steam Deck. On a native Linux machine it’s easier. I don’t see a way to install OpenSnitch on the Steam Deck with the read-only file system and whatnot. I think a pi-hole and block DNS might be easier than trying to mess with SteamOS.
