Cheats nowadays don’t even need to run on your machine. You can get a second computer that is connected to your computer via a capture card, analyze your video feed with an AI and send mouse commands wirelessly from it (mimicking the signal for your USB receiver).
These anti-cheats are nothing more than privacy invasion, and any game maker that believes they have the upper hand on people that want to cheat are very wrong.
Opening up anti-cheat support for Linux would at least make them more creative at finding these people from their behaviour, and not from analysing everything that’s running in the background.
