I've always hated middle-click-paste, but trying to turn it off quickly rears a bigger issue, it's somehow deeply embedded in Linux, disabling it in Gnome would leave it enabled in other places like FireFox, which leads to searching how to disable it, which leads to recompiling the kernel, at least that's the rabbit hole I went down last time. I have no opinion on whether it should be default or not, but I wish it was easier to control globally.
