Would you also find it to be a problem if they held a meeting and didn't serve fair trade coffee? Should they expel any members with politics you find objectionable? Must they demand that everyone give up their iOS and Android devices too because they're surveillance instruments and running non-free software too?
Here's a good Tumblr post this made me think of:
- [The Grey Tribe — Activism, Accessibility, Setting Good...](https://the-grey-tribe.tumblr.com/post/175038067648/activism...)
that being said, get involved and get them in Matrix or IRC, not too difficult to enact change I think people could get in on it with appropriate leadership!
zulip looks interesting to me as well.
I think the best I can do at this point is set up my own server running Matrix (or Zulip, which I haven't really explored) and host my own bridge to ease the transition. It's the classic problem where, now that I actually have money to spend, I don't have free time or infinite energy for side-projects anymore.
Mattermost is nice but it's not federated and I don't think it will catch on as a "public-facing" chatroom option. It's a nice solution inside an organizations that doesn't want to pay for Slack. I haven't used Rocket.chat but it looks similar along those lines. Wire just doesn't seem like the right solution.
