Their general point of view is definitely not wrong.
When it comes to music, I've had a good time using Reaper for casual guitar recording, however a bunch of my plugins struggle horrible with Yabridge. A lot of this stuff has online per-system drm these days, namely anything from NeuralDSP, so that often puts it to a halt
I have zero issues whatsoever, even on Nvidia. Even before the 560-series driver, my issues were slim to none. I've been exclusively on Wayland since Plasma 5.22, and even before that with GNOME, just because it's astronomically more smooth visually
