Cons
Con Won't work out-of-the-box on the most PC's
Almost all PCs need non-free drivers but Parabola has none to offer.
Con Same cons that apply to Arch Linux
Con Not compatible with AUR
Unlike other Arch-based distros, this free distro doesn't support AUR.
Con Small repositories
Since Parabola is a completely free distro, there is no non-free software available and the community repositories are small compared to the AUR.
Con Incompetent developers
They only care about removing "non-free" software, rather than making a properly working OS.
Con Serves no purpose
It's just Arch without non-free software and is basically a niche OS with few users.
Con Not really free
People have to pay hundreds to maintain this distro.
Con No systemd
Some packages flat out won't work because systemd is non existent, sadly pipewire needs systemd to run. Hopefully Pipewire becomes usable soon. Edit: Pipewire does work but you will have to make a startup script.
Con Few Arch packages might not be available yet
Developers are working migrating all packages into their own repositories while ensuring there's no systemd malware.
