In my case I switched from kubuntu to Manjaro because the Firefox snap not only had annoyingly long cold-start times, but also broke the browser integration plug-in for the Plasma desktop. So the integration between my default desktop and default browser was broken by a Canonical policy decision.
I know I could have removed snaps installed a native Firefox via a PPA, but decided I didn't want to waste time fighting my distro.
I assume other desktop apps will get the snap treatment soon eg libreoffice, thunderbird, VLC etc and the user experience will be like wading through molasses.
