What percentage of Linux users similarly don't care about their window manager? I know Linux users split off to their own distro/tribe for all sorts of technical and aesthetic reasons. I kinda wish there would be a consolidation of effort behind one stack if for no other reason than to give macOS and Windows a proper challenge. Perhaps with the Evil IBM acquiring Red Hat the "last free distro standing" behind which everyone can rally could be Debian/Ubuntu? I'm fine with that.
