Listen, I don’t know what goes behind Canonical’s backs, but I think we are just trying to get more community involved because we really express it, but not much on Twitter. Other distros like EndeavourOS are, too.
Canonical board leaders own it, and they are probably just trying to pull the community together, and give all the Ubuntu community members a part of the Ubuntu that they want, like some will stay Lubuntu, some maybe when it comes out Ubuntu Cinnamon.
And discourse isn’t known much, so its great for support. There is also @ubuntubot which is where support can be given by other people.
Anyways, in conclusion, just to get this (i think) useless article off-Canonical runs it, and so does its main leaders that are most likely trying to get the community involved.
