While I do share your frustration on linux gaming I thought to give sound to the opposing side who simply had this coming oit of a risk analysis.
TL;DR - it's indeed much easier to cheat on linux
After decades of fighting wars with crackers/reversers and all anti-debug/anti-cheat methods proven unusable against russian teenagers, AAA companies reached out to microsoft to get their undocumented binary "drivers" into the system which you cannot inspect from userspace.
With linux coming into the party, even if with the amazing work by Wine you do manage to get the desired anti-debug behaviour on the emulated userspace app, linux people can make arbitrary hooks on their kernels.
So instead of risking major reddit shitstorms over that 1% players that can cause 3% profit loss, it's better to ditch that 1%
