Reliable Anticheat rootkits are just not possible on Open PC platforms. Consoles should just add proper keyboard+mouse support and competitive online players can move over...
Nowadays you can mix&match however you like. I have one game that is available on PS, PC and mobile. You can use keyboard, mouse and PS controllers in this game on all of the platforms and it works the same. For now, I mainly play it on linux (it's not linux native game, heh) with ps4 controller.
