@mdiluz for folks thinking of considering Matrix, please stay away. It has the most unusable UX, and I have a running list of companies/clients who have moved away from Matrix (Element) back to Teams/Slack/Mattermost.

Usability is an issue that Matrix has willfully chosen to ignore under the garb of "Decentralized and secure messaging".

@mdiluz

Mattermost has essentially given the OSS community the middle finger.

To make matters worse, they have a 10k message team edition (self hosted as well)
