First off, if you read the other replies you would've saw I said that I understand making a linux build takes time. As someone learning how to code I understand all too well how much work it takes to make a linux build.
Secondly, not every has the same specs to run a game at full frames, like me for example I've ran the game in proton after a suggest from another reply, however my specs are nowhere near good enough to run the game.
Thirdly, some people just want the ease of having a game that just runs, running proton and a bunch of other apps takes up resources, can cause potential compatibility issues and more.
I'm not trying to be rude or anything, just kindly asking them if there was any plan to make a build in the future, that was it.
Edit: I want to add also that using Proton and other apps similar to it makes debugging hard for a casual user who just wants to plug and play cause Proton adds it's own issues, resource overhead and more.
I'm sorry, but a native build is just simply far better in the long run, not everyone has the time or patience to deal with Proton, dig through thousands of lines of text for a crash log only to find out it's related to Proton and then have to get frustrated cause it's completely out of their hands.
A native build cuts that out and makes crash logs, bug reports and more so much easier to get through. And it lowers resource overhead for lower end systems cause not everyone has thousands to spend on a high end PC
