You still haven't explained why e.g. Zulip
I think that Zulip is a good service and AFAIK Zulip is the OSS project based on Python. But I think that such communication tools should be evaluated not only technology side but also on how people feel familiar with UI/UX. I don't want to evaluate the UI/UX accessibility of Zulip is good or bad but it's the issue of how people feel familiar.
I don't think that's an important concern. We're talking about chat systems, which are all really approchable. If you're not familiar with Zulip, it will take little time before you can use it reasonably well. Same for Slack, Discord, Gitter... and also Discourse, by the way.
On the scale of UI friendliness, all those systems are on the "easy" side (compare with the git CLI, which is on the "difficult" side).
This phenomenon also occurs in other common (non-business) messengers. (WhatsApp, Facebook Messenger, etc..) You can observe that there is no single monopoly messenger which concurs worldwide.
Mostly because people go where their friends / colleagues / acquaintances are. In other words, those are network effects and have nothing to do with the UI friendless of each system. For example, I have to use Slack at work, yet I find Zulip far more convenient.
