ridiculous, Is it also fords fault I cant use an f150 because I live on a mountain without roads? You may have purchased hardware that has explicitly chosen to make life difficult for anything but windows, that is hardly "because linux". Nobody is even asking THEM to make drivers, which allthough would be nice, everyone would settle for "tell us how to use the hardware", or at best "dont actively prevent us from making drivers".
And why can you not use the monitor?
Your discord problems are almost certainly caused by you doing it wrong. Linux is not a magic solver of problems, you know your way around windows, but if you invested same time into learning linux as you did windows, you'd know how to do things there aswell.
