Matrix is an incredibly centralized service masquerading as an easily self-hosted distributed service. The moment you try to get a non-technical user connected to a homeserver other than matrix.org, all hell starts to break loose.
It's bad enough that both France (tchap) and Purism have created their own client forks to make on-boarding somewhat tolerable at the expense of really painful rebases against upstream Riot, while Riot tries to get it's shit together on the non-matrix.org user story.
Mattermost has a slightly less painful situation -- they provide a relatively easy to brand/preconfigure client (and fantastic docs on how to do so: https://docs.mattermost.com/mobile/mobile-compile-yourself.h... ), but you lose out on federation and self-service sign-up, leaving your community isolated (sometimes a pro, sometimes a con).
