I think the point is that any system which is meant for people to self-host AND which is based on a Linux distro (Debian, Red Hat, etc. -- YunoHost is based on Debian) is broken by design. Running "sudo apt-get update" and "sudo apt-get upgrade" in a cron job is not a security solution. Operating systems have to be designed so that a security hole in a single application can't compromise the entire system. If not, I would argue they are unsuitable for the average user to "self host". Modern Linux distros don't meet this criteria. OpenMirage is solving some of the same problems as YunoHost, just on a longer time scale and with real solutions rather than hacks piled on top of hacks (I'm not affiliated with the project). apt-get is a big hack and not suitable for distributed computing.
