Even if you don't play PC games this is slowly becoming a massive problem across anything competitive or online-based. Companies, in their tryst with cheating, are justifying ways to run anti-cheat software along with the game during online sessions. Now, the reports always say this doesnt affect consoles but then I ask how long before even that statement becomes obsolete? It's not like you can't hack a console and its not like they can't cheat there as well. Shame really as I like Doom Eternal and before this May 14th patch I was seriously considering a second run with the difficulty all the way up as well. The good news is that Bethesda is removing Denuvo, the bad news is that a lot of folks who installed it with Denuvo on there won't really know if its gone or if it still around somewhere.
Ring-0 is not for software that is not from the OS provider, PERIOD. And if something does require that level of access then the OS provider needs to be involved along with a security team chosen by the international community (this sounds like a joke but its not). The last thing you want is for some lazy security programmer pushed by the boss on a deadline to introduce a hole and then forget stealing data from your machine they can do far far worse.
