I've been pretty consistent with the "GNU/Linux" phrase, but recently have switched to "GNU+Linux". I had not heard of Sway but I see it "is a tiling Wayland compositor and a drop-in replacement for the i3 window manager for X11." I'm not doing Rust but instead of recommended Go. I don't have strong opinion/knowledge on the "RMS drama" other than saying I've decided the FSF is still worth supporting.
