“Kernel” anticheat isn’t really any more dangerous than any other executable you run on Windows. Code from untrusted devs isn’t safe whether it has admin or not. Games made by small devs are much more dangerous than anything put out directly by Riot or Valve.
Remember when Sony automatically installed a rootkit on customers’ computers if they put in their legally purchased music CD to listen to, that was a security vulnerability that hackers quickly found and exploited? Pepperidge farm remembers.
Incompetence is just as dangerous as malice, and big companies have shown they don’t bother to take the care needed to protect your device.
