Thanks for taking the time to share your sentiments!
The majority of the Factorio player base uses Windows as operating system, hence I created it initially with Windows in mind. As the mod and launcher is fully open source and made in Electron you are however welcome to either compile it to Linux yourself or create a pull request that adapts the CI/CD pipeline accordingly. Not everyone uses Arch btw.
Also let me in on a little secret: Nobody forces you to download or use this mod. No reason for you to try to take it away from those that do.
Lastly, I'd advise you to consider transitioning from an unhappy person to a more happy one.
