Con Slower updates
Updates are slower than an unmodified Debian.
Con Difficult to install on non-free hardware
Unlike Debian, Devuan offers no unfree netinstall media, so if your system needs unfree drivers (e.g a laptop or a tablet), you'll have to download the Debian firmware on a separate USB.
Con No systemd
Con Fragmentation
Forked distributions like Devuan and Artix fragment the Linux community and hurt the original project. Debian users who do not want systemd should use Slackware or BSD instead.
