Who is accusing Linux as the cause of anticheat not working? I haven't ever seen that, I see people blaming the anticheat creators for not supporting Linux, they know Linux is not the one at fault yet they still want to play games therefore they use Windows instead.
You didn't read the thread? It's the comment I was replying to: https://news.ycombinator.com/item?id=47718255
They quote "If a game has an aggressive anticheat" and then state "The determination of the average Linux user to ignore the faults of Linux", which is accusing Linux of being at fault for the aggressive anticheat not working.
