That’s very clever, I would’ve just deleted the file & the updates would’ve brought it back. (and TIL you can do this)

Overall it sounds much better to me than windows anti-cheat, but that’s a pretty low bar.

I think all the things you are saying are just claims. As far as I understand it, this will be closed source software that runs as root, so basically it’s just trustmebro, the same as on Windows. I’m not a systemd expert, but seems challenging to fulfill the part where it “only runs when the game runs”.
