@freetechproject #Manjaro relies on #Amazon to distribute its user guide (osdn.net). It's not an exclusivity problem but some would have ethical objections to that.
#KDEneon is #ubuntu-based, which means it supports PPAs (not good). It'd be better if it were based directly on Debian to encourage apps to become official #Debian & enrichen support of the OS with higher QA standards.
I've not used either distro so I didn't vote.
