there’s no way for users to reliably remove it
I’m not sure if this is true for the ones backed by the larger companies, like EAC. It’s possible to completely remove EAC using their installer.
Games like valorant are filled with cheaters despite using kernel anticheat
In my experience, this is untrue. Valorant isn’t “filled” with cheaters in the same way Apex Legends is.
Some anti cheat work better than others, and it depends on how much you’d like to play the game that needs it. Plenty of games without.
EAC does not hide its process and you can see it running. If it’s not, perhaps it has left files behind, but that’s a Windows issue more than EAC’s.
