@sir What alternatives could you suggest? IRC is text-only and primitive and Matrix is slow and I haven't yet seen a client with decent UX. I haven't used Zulip or Mattermost yet, I've only heard of them.
@phoe IRC is king, text-only is a feature not a bug
It's a pity, since it worked perfectly fine, was self-hosted and had features that Slack still lacks (for example, the ability to implement bots that push custom HTML in replies).
