Given the plethora of at-least-as-good #libre messaging platforms (see Matrix, Rocket.Chat, Zulip, Mattermost, NextCloud Talk, etc.) that aren't
* exploiting your data,
* pestering you to pay more,
* reducing 'free tier' features (to get you to pay $),
* 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.
