Given the plethora of at-least-as-good #libre messaging platforms (see Matrix, Rocket.Chat, Zulip, Mattermost, NextCloud Talk, etc.) that aren't

- blocking integrations you want,
- failing to live up to their security promises, or
- simply being painful to use.
Why does anyone bother with MS Teams, Salesforce Slack, or Discord? Just doesn't make any sense to me.
