Yes, it’s invasive kernel-level anti-cheat common in competitive multiplayer games now, because cheaters will mod their system that much for the sake of getting around the anti-cheat. Annoying from all sides.
That, and despite many devs being Linux fans, there does seem to be a (false) perception that Linux is the OS of choice for cheaters.
EDIT: Just remember, can’t play a game on Linux? It’s ALWAYS either the DRM or anti-cheat. Either way, corporate BS that hinders honest paying customers more than the people it’s trying to stop.
Lutris does most of its updates from within the app itself, so it only really needs packaged releases when there’s an update that can’t be done from within itself.
