The issue with this entire statement is that despite the amount of system access they want, and the complexity of the software they've made, cheating is as rampant as it was before. The fact that they continue treating Linux as an issue, just as Ubisoft do with Siege, or Bungie with Destiny, just shows that there is a much larger issue at hand
Even worse, it proves that they themselves don't understand the entire psycho-social scope and workings of cheating. Cheating is not an entirely technical problem. It's multidimensional.
