Riot is not implementing the same kernel anti-cheat for Mac. In their blog post, the noted that there are about 800 users playing League through Lutris. If they can detect this, why can't they just allow Linux users to play without the kernel anti-cheat.
I don't think there is a single League of Legends player in the world that wants a kernel anti-cheat. Riot did it anyway. They are completely out of touch with their user base. How are people supposed to trust a kernel anti-cheat from company that is owned by a Chinese company, Tencent.
