The OS itself offers no structural resistance once root is obtained — it can write to system directories, replace binaries, install kernel modules, modify boot configuration. None of this requires exploiting a vulnerability. It’s just what root can do by…

Meanwhile on PC, kernel-level cheats, rootkits, and firmware-level malware are a constant concern that entire security teams spend careers fighting. That’s not a coincidence. Console manufacturers made a set of deliberate architectural decisions that PC…
