Have you ever worked in the games industry? Anything that has to be done costs money and needs to be very well justified. Making working Linux builds and testing them is not just switching a compiler flag. It's a multi-week project that needs to be funded and takes away developer resources from actually making the game good, for an absolutely miniscule userbase that could play your game just fine without any drawbacks in Proton, for free. Valve pays for it because developers can't/won't. Even if you fund a Linux port, it basically ends up abandoned because there is no money to maintain it - updates will only go to Windows. There's even games that don't have working DLC in their Linux-native versions.
