Matterhorn is a command line Mattermost chat client. I built the matterhorn snap back when I worked at Canonical, where we use Mattermost. I no longer use Mattermost, so am not using matterhorn at all. So I don’t think I’m best placed to own the snap. If someone else (preferably someone who uses matterhorn/Mattermost) would like to take it on, that would be great.
It only has about 200 weekly active users (probably many of those are Canonical employees). The upstream project isn’t super active, but does get some updates here and there.
I don’t like punching users in the face for something which is a developer ask. I’m fine if it was recommending they switch to a different, well maintained snap (as we did with other snaps like irccloud). But to ask for them to maintain it, doesn’t sit right for me. I’ve made the snap unlisted and archived the git repo. If someone else wants to pick it up, it can be transferred and someone can fork the repo.
