My research group still uses Slack, which is not only USAian, but also has a terrible free version and expensive subscription.
I am confident there is will to switch, but the inconvenience of learning a new platform prevents the team as a whole. What would be good alternatives that would make an easy transition period?
Isn’t Mattermost basically open source Slack?
I’m not fully informed, but mattermost changed its license (still open source) and some aren’t recommending it anymore.
Maybe the Talk app in nextcloud would be enough? https://nextcloud.com/talk/
Element (matrix)?
https://prose.org/ looks great, it even uses a standardised protocol. I’ve tried it and it works well, much better than Rocket.Chat, Zulip or Mattermost.
